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.
