OK, here are the results of my initial tests.  See ++ TEST ++ at
the end of these notes for the results

Description    :
Perl is a language that combines some of the features of C, sed, awk and
shell.  See the manual page for more hype.  There are also many books
published by O'Reilly & Assoc.  See pod/perlbook.pod for more
information.

***************

Now read the article: 
https://forums.freebsd.org/viewtopic.php?f=5&t=46523.  We are
going to do some of the steps,  with minor modifications.

1. Install apache24
    #> cd /usr/ports/www/apache24
    #> make install
   OR
     pkg install apache24

2. Start to install mod_perl2, fetch the source code:

    #> cd /usr/ports/www/mod_perl2
    #> make fetch

    This will fetch mod_perl-2.0.8.tar.gz and put it in /usr/ports/distfiles
    Now untar mod_perl-2.0.8.tar.gz

    #> cd /usr/ports/distfiles
    #> tar xvf mod_perl-2.0.8.tar.gz

3. We will create a dummy mod_perl-2.0.9 distribution file.  We
    will need the Apache-Reload, Apache-SizeLimit, and Apache-Test
    Perl Modules from mod_perl-2.0.8 ,  which are not in the SVN
    distribution we are going to fetch,  but are in the mod_perl-2.0.8
    distribution.  Note that these appear to be the latest versions;
    if in doubt check the Apache Web site.

    #> mkdir mod_perl-2.0.9
    #> tar cf - -C mod_perl-2.0.8 Apache-Reload Apache-SizeLimit 
Apache-Test | tar xvf - -C mod_perl-2.0.9

4. Now get the latest http24 branch from the Apache Mod_perl SVN repository:

    You may need to install wget:
    #> pkg install wget

    #> wget --no-parent -r 
http://svn.apache.org/repos/asf/perl/modperl/branches/httpd24/

    This will create a 
svn.apache.org/repos/asf/perl/modperl/branches/httpd24 directory.
    Now we copy these files to the mod_perl-2.0.9 directory:
    #> tar cf - -C 
svn.apache.org/repos/asf/perl/modperl/branches/httpd24 . | tar xvf - -C 
mod_perl-2.0.9
    #> ls mod_perl-2.0.9
    Apache-Reload           LICENSE README                  
bin                     t
    Apache-SizeLimit        META.yml README-SVN              
build                   todo
    Apache-Test             Makefile.PL RELEASE                 
index.html              util
    BRANCHING               Makefile.old STATUS                  
lib                     xs
    Changes                 ModPerl-Registry SVN-MOVE                patches
    INSTALL                 NOTICE WrapXS                  src

5. Create a tar file of mod_perl-2.0.9
    #> tar cfz mod_perl-2.0.9.tar.gz mod_perl-2.0.9

6. Now we modify the www/mod_perl2 port

    #> cd /usr/ports/www/mod_perl2

    Edit Makefile, and make the following changes:
    a) we set PORTVERSION to 2.0.9
    b) we set USET_APACHE to 22+
    c) remove the 'Broken' warning

6. This is a bit tricky, and thanks to the Ports folks for showing me this.
    First,  We now set the checksums in distinfo.orig to match the newly 
created tar file:

    #> make makesum

7. Now for the acid test, we try to compile this:
    #> make build

     (See build.log)

     ++++++++++++++++++ TEST ++++++++++++++++++
     But Does It Work?
     See next section for detail
     ++++++++++++++++++++++++++++++++++++++++++

8. If we want to install it, we should update the pkg-plist:
    #> make makeplist >pkg-plist

    #> vi pkg-plist
    Get rid of junk lines, delete from the first line up to  and including
    /you/have/to/check/what/makeplist/gives/you

9. Now you can try to install it:

    #> make install

10.  You now need to edit /usr/local/etc/apache24/httpd.d and add:

   LoadModule perl_module libexec/apache24/mod_perl.so

  ++++++++++++++++++ TEST ++++++++++++++++++

After all of this effort,  I expected mod_perl2 to fail all of the
tests.  The mod_perl tests cannot be done by root so you will have
to use another user.  First you will need to set up a suitable test
user.  AND...  Part of the tests require writing a file to /var/run.
AND... during the tests you will write a log file to the t/logs/\
directory in the mod_perl source.

So...
1. Create a user say, admin.
2. Add it to group wheel (see FreeBSD Handbook).
3. #> ls -ld /var/run
    drwxr-xr-x  12 root  wheel  1024 Aug  2 19:03 /var/run
  . #> chmod g+w /var/run

4. #> cd /usr/port/www/mod_perl2
    We need to set ownership of the work directory to the test user:
    #> chown -R admin work

5.  Now we run our tests as user admin:

    #> su admin
    %> make test |&tee test.log

Here is an extract from test.log showing the failues. Note that
most of the failed test are for Apache,  and may be common to the
baseline Apache distribution.

    # Failed test 5 in t/apache/scanhdrs2.t at line 33

      I suspect that this test is due to the change in the API from
      2.2 to 2.4.

    # Failed test 4 in t/hooks/authen_digest.t at line 35
    # Failed test 5 in t/hooks/authen_digest.t at line 37
    # Failed test 6 in t/hooks/authen_digest.t at line 41
    # Failed test 7 in t/hooks/authen_digest.t at line 45

      Again,  apache22 authentication support (Allow,deny) is now
      obsolete.  See http://httpd.apache.org/docs/2.4/upgrading.html
      The 'Order deny, allow Deny from all' is now 'Require all deny'

      I suspect that these tests might need to be updated for
      apache24 or separate tests done for apache22 and apache24

    # Failed test 2 in t/modules/cgi.t at line 35
    # Failed test 5 in t/modules/cgi.t at line 60
    # Failed test 3 in t/modules/cgi2.t at line 43
    # Failed test 4 in t/modules/cgipost.t at line 34 fail #4
    # Failed test 4 in t/modules/cgipost2.t at line 34 fail #4
    # Failed test 1 in t/modules/cgiupload.t at line 36
    # Failed test 2 in t/modules/cgiupload2.t at line 36 fail #2

      I suspect that there has been some change in the API for CGI
      support.  This needs to be reviewed and the cause
      of the failure determined.
