(I'm resending this as I did not see it go through the first time)


I was running into a problem trying to build MP2 with a name other
than mod_perl.so.  After poking around for a while I found that the
MP_LIBNAME arg on the command line was not replacing the default
value of mod_perl.so, but just appending it.  So if I specify something
like:

        perl Makefile.pl MP_LIBNAME=mod_perl-2.0_cvs

I get back something like:

        mod_perl dso library will be built as mod_perl mod_perl_1.99.10.so
        mod_perl static library will be built as mod_perl mod_perl_1.99.10.a

Anyway, I patched lib/ModPerl/BuildOptions.pm so that you can tell the script
whether you want to append the command line arg or replace it.  The patch is
included here, but someone should check to make sure that the options I have
selected as appendable/replaceable are in fact such.


thanks
Andrew
