If you make a "free standing" .exe with their PerlApp, you can distribute that at will with no restrictions to anybody that you want to. That is how I distribute my .exe code.

Now that means that this .exe comes with 1MB+ of "baggage", the Perl execution engine for every single ".pl" program. But in today's environment, that size is of no concern in a practical sense.

But this is correct, you cannot "re-distribute" their Perl. They want you to go back to the "quelle", their source for a Perl system download so that they maintain control of versions and for other marketing purposes! But a single Perl program made into a free-standing .exe with their PerlApp program - not pp, can be freely distributed.
