You'll need to reinstall mod_perl from scratch when upgrading Perl.
Typically this includes recompiling Apache as well, as mod_perl is
statically included in the httpd binary.  It looks like you may not
have done this, and httpd is looking for the older perl stuff still.

Be sure to use your new perl binary when running the 'perl Makefile.PL'
step for mod_perl.

mod_perl is a bit more difficult to install that most CPAN modules.  If
you've never done so before, then this will help:
  http://perl.apache.org/guide/install.html

There's alot there, so if you need a quick fix try:
