Hi.

About your problem below...

I am not sure that this is going to help, nor even if it is really 
relevant to your specific problem.  Just trying to give you ideas, 
because it reminds me of something.
Below are two configurations, of two of our systems which have slightly 
different versions of mod_perl and the rest.
I went through the same kind of problems you're going through, a while 
ago when going from Apache 1.x to Apache 2.x, and then again more 
recently when there were some changes in the mod_perl naming of modules 
between mod_perl 1.9xx and mod_perl 2.0, and then some additional things 
happened during a Linux Debian upgrade from Sarge to Etch, which changed 
the location where some Apache2 stuff was installed.
And there is still some difference to this day in some Perl scripts or 
modules between these two systems, which greatly bothers me, but it 
basically works.

The main difference is in the two first "use" statements in our 
"startup.pl" script (which I assume you are familiar with, as a way to 
pre-load some perl stuff when the server starts).
I do not remember precisely which problems we had, but they were of the 
same "general gist" as yours, so maybe this helps.
Here it goes :

1) system "colin"  (Debian Sarge, older)
=================
version (uname -a) :
Linux colin 2.6.8-11-amd64-k8 #1 Sun Oct 2 21:26:54 UTC 2005 x86_64

Apache2 version : see below
Perl version (perl -v) : 5.8.4
mod_perl version (per Apache log) :
[Wed Feb 13 22:24:59 2008] [notice] Apache/2.0.54 (Debian GNU/Linux) 
DAV/2 mod_jk/1.2.6 PHP/4.3.10-22 mod_perl/1.999.21 Perl/v5.8.4 
configured -- resuming normal operations

mod_perl "startup.pl" script :  (invoked via "PerlRequire" in httpd config)
------------------------------

#!/usr/bin/perl
# modperl2_startup.pl
# Apache2 / mod_perl 2 startup script

   use Apache2 ();
   use Apache::compat ();
   use lib "/usr/lib/apache2/perllib";   # that's a local perl lib directory
   use lib "/home/EFS/lib"; # that also

   use CGI ();
   CGI->compile(':all');
   1;

2) system "arthur"  (Debian Etch, more recent)
