Check the Changes* files for the Perl distribution that you just built into mod_perl. There was at least one thing that was being overlooked by taint checks that is being caught in the latest versions of Perl. The details of this change may be a big clue what to look for.

I somehow think it will be hard to get assistance from mod_perl on nailing this down. So I'd run the script using "regular" Perl of the same version that you just built into mod_perl and see if the same problem appears. If so, I'd use the perl debugger to get more details.
