Re: Perl module license clarification

The following cannot and should not be construed as legal advice. I am

That's the question that is being asked. Is that really what they mean?

The main problem I see is that the terms that the program is released
under is (possibly) a moving target. What rights are guaranteed at
some time in the future isn't known. [When using such a license you're
basically asking for the court system to sort the legality out.[1]]

Your missing a key phrase here: "any later version AT YOUR OPTION."

In this case, the GPL version 2 is known to apply, as could any other
version of the GPL. While it implies a sense of trust in the authors
of the GPL, the terms under which the program is released are at least
GPL version 2. This is not the case in the perl module licensing
