>> Oh, and now is a good time to review How do I post a question effectively? :)

I did say “But I added another file in the same directory as the .pm file, that is "required" by the code at run time”. I did not say that I was adding another module to the distribution; it was "some file", and although I didn't spell it out, it should have been clear that whatever it was, it was not a .pm file.

So maybe you can stop hiding behind Anonymous, and perhaps read a little more closely and answer what was asked. Or be a little more polite with pointing out that the root of the problem wasn't as explicit as it could have been (after all, had I know it was significant I would have known what to look for!!) rather than treating a 10-year PM veteran like a noob.
