I am aware of these issues. I replied in-haste in-class, and didn't specify that I was only referring to library code. I instead used 'work', which was the wrong term; I apologize. Anyway, according to the GPL, using a GPL-ed library as a dependency in a larger codebase constitutes a derivative work (assuming distribution etc), thus requiring GPL-ing the whole larger codebase, which isn't cool (imo, of course).
