Yeah. Below is your problem.

I said "perl's" cause it make _sense_. mod_perl has own libperl file and 
perl itself has one. '/usr/local/libexec/apache/libperl.so' - mod_perl 
DSO library.

And this is your problem. it's perl's libperl files that should be 
placed into other dirs(like below with 5.8.5 when you have more then one 
perl).

If you want replace old perl with new then you can rm old files from 
/usr/lib/ (don't forget to *backup*) then may be(don't know) you need 
rebuild mod_perl.
