I built 5.14.12/2.2.24/2.08-dev yesterday on a Centos 6.2 box.

Thinking Perl needs to be recompiled with -fPIC. Your httpd loads a
certain mod_perl via PerlRequire in httpd.conf, which grabs the
appropriate mod_perl.so, which is linked to the version of Perl it was
compiled with. If you get undefined symbol errors, you probably need
to recompile your httpd, but I've seen this before and a Perl
recompilation resolved the issue.

Suggest trying with the 2.0.8 release candidate and reporting back on
that email thread.
