So why does it say it can't find the module? I know it's there. The cgi script runs under user www, but the permisions of the module and containing folder are 777...

What do I do?

First, you post the exact error message here (inside <code> tags, mind you). Then we'll see.

I'd write a small CGI script which tries to open the module file in question (dying $!). If it barfs, I'd try to chdir where the module file lives, splitting the path and going down each folder. That would give clues.
