The GPL has very clear terms for how I can make copies of derived
works. One of those terms is that the complete derived work doesn't
have any additional restrictions above what the GPL has.

Other licenses may not care about derived works, but the GPL does.
This is particularly true for the graph library, since the binary will
contain large chunks of it.

I didn't say that I had a problem with it's freeness. Rather it is
incompatible with the GPL. This is the same kind of clause as caused
problems with Python.
