I'm wondering if it's picking up the correct glut (the one that comes with Mesa in the demos package) or another version on the computer. (Because normally Mesa more-or-less behaves itself.) I'm not sure how easy that will be able to determine since it's crashing before it gets very far. (In case you haven't yet, you could try a blank project and just create a new window, i.e. without opening any spectra. If that works, in the sense of opening the blank window without crashing then that would mean that GL by itself is probably ok. But I guess the odds are even that would crash because it's possible just loading libraries is causing the problem.)
