You may be better served to add your path to your modules with use lib '/path/to/modules';, this will add that path to @INC.

Are you using a different version of perl other than what mod_perl was compiled with? If you've upgraded perl, you need to recompile mod_perl, too. Your paths will likely be different in your different perl versions.

If you're using Apache::Registry to speed up existing scripts and have a perl version mismatch, you may be able to "use lib" to the old version of perl, or change your shebang line to reflect the perl install you want.

Before we go too far down this path, do you have more than one version of perl installed on your server?
