in reply to Perl modules and the GPL

And, thankfully, most code on CPAN is dual-licensed (though not always obviously so - sometimes it's in the POD, which makes it very difficult to abide by the lawyer's rules that I can't download the code without corporate approval, and I need to tell them what license it's under...).
This should not be an issue, provided that your lawyers are OK with you viewing web pages. Just look the module up on CPAN and click the "Source" link in the upper left of the page. If there's a license statement anywhere in the module source, you'll be able to see it without "downloading" the code.

    I say, if it's on cpan it's fair game no matter how you cut it. After all, for software to be useful it most typically needs to be distributable. I'm just saying there is a significant implied license (although I know that lawyers don't like that).

    From cpan contributors part of the faq:

    However, I was surprised not to be able to find a place where you must agree to a license to upload.
