That is useful info. Let me ask this; you don't by any chance have ActiveStates Perl installed independently, do you?
those are all Perl Module fails. Does Oracle Apps have its own Perl install? (not a tool I am familiar with).
Also, do you know if you need mod_perl?
Perl programs have to be constructed in a particular fashion to run with mod_perl. If you are using Perl scripts not developed for XAMPP, you may wish to try disabling mod_perl. YaBB (something I know well) does not run with mod_perl loaded.
you can disable mod_perl with setup. it might
be a quick fix.
