The math is really very simple:
GNUstep: LGPL => links with any license you want
DevIL: LGPL => links with any license you want
GLEW: MIT/BSD => links with any license you want
PRNG: GPL => links ONLY with GPL
NVIDIA Cg => no idea on usage license terms
In other words, you'll have to use GPL for your app. Remember, that GPL
linking requirements only work from library -> app, i.e. if you link to
a GPL library, your app has to become GPL. If, however, your app is GPL
and you link to a non-compatible/proprietary library, that doesn't force
the library to become GPL. As an example, consider compiling a GPL app
against Solaris' proprietary libc - that doesn't force the libc to
become GPL. That means, you don't have to remove the NVIDIA Cg
dependency if you don't want to.

That brings me to my next question: What licenses are available to
me, if I use/link with GNUstep?
GNUstep uses the LGPL, which means any license from public domain to
first-born child required to use is acceptable for code that links
with it. Pick any license your comfortable with. Most of Étoilé
uses BSD or MIT licenses, a number of frameworks built with GNUstep
use the LGPL and a few use the GPL.

There are a couple of libraries I use. DevIL is LGPL, GLEW is licensed
under 2 similar MIT licenses and a modified BSD license, PRNG is GPL.
As far I can tell the license NVIDIA Cg is under is not free software
compatible, so I will have to remove the dependency on that library
before I actually get an svn repository at sourceforge, sic.
