GPL prog + free proprietary module

Ok, so whenever I see the question come up about combining GPL and proprietary software, it's almost always the proprietary dev asking can I use GPL code. My question is, can a GPL'ed program require a (free) proprietary module to work, by not distributing that module and just telling the user to go get it (provided the user can legally obtain this module, and in this case, for free)? My guess is yes, as in say the LAME plugin for Audacity. Just want to clear this up.

Nope

I'm quite sure the answer is no. The LAME plugin is GPLed.

Sometimes, the impossible can become possible, if you're awesome!

GPL, but patents cause trouble

The reason why LAME is not included with various packages is that the MP3 format is patented and the owner of the patent causes trouble, but did finally permit the hosting of the LAME program in one spot, but it may not be redistributed unfortunately.

The question here though is whether or not a GPL program can use a non-GPL download. The answer is yes.

Forgive my ignorance...

But doesn't a patent completely contradict the GPL?

No

The patent is not theirs. They've been given permission to use patented content.

But let's not get started arguing about stupid software patents... Blum

Of course

So long as it's not distributed with it, it's fine. Your GPL program can do what e'er it will once it's installed.

My mistake

My mistake with the bad example. And no, I am not planning on distributing the $0 non-OSS program. Thank you.
