i think Apache is unable to load your Optrack module, because it does not find it in @INC. try adding your path to the module in httpd.conf, something like this:

PerlSwitches -I"C:\path\to\your\module\"
[download]

then delete the line:

PerlRequire Optrack
[download]

and use your module from Apache like this:

PerlModule Optrack
[download]

you can read about passing arguments to Perl from Apache in the mod_perl 2: Server Configuration Guide: Perl Switches.

hope this helps
