Re: Automake: use of modified Perl modules & GPL

[Richard Stallman]

    We would like to have some advice from you about a license issue.  In
    short, we would like to use a modified version of a Perl core module,
    which means we need it to be GPL.

I don't understand the scenario clearly, so I don't know the answer.

Who initially wrote this module?  What license was the original
version released with?

Who wrote the modified version?  Was the modified version ever
released?  Do you have a copy of it?  What does this modified version
say about its licensing?
