Well, it's a bit of a recursive issue. If the OP can't use CPAN, the OP definitely can't use code written for him/her here. The same legal issues would apply and they would generally be much worse. Everything on the CPAN is under some kind of open source license. I post code here all the time and I don't think I've ever listed a license against it. I don't think most monks have. Which means most of the code here is not open licensed and a legal risk for anyone to use.
