From this Zlib FAQ entry, I would deduce that it's not illegal to write and use a program that is compatible with compress, but you cannot distribute it without a licence, not even for free, and a licence would cost you a lot of money.

I don't think there would be a real problem with, say, a Compress::Uncompress module which only uncompressed .Z files. I say so because gzip does so. It just doesn't create them.
