Please your suggestion to help the OP. I am trying to do so.

Update: my brain wasn't running at full speed - If you are making an .exe with PerlApp, I've found the easiest way is to just add: use Net.pm; to the source code instead of fiddling with these other parameters. The Net.pm probably came in as a prerequisite to some other package rather than being explictly installed. Any package that is "used" will wind up in the PerlApp .exe.
