Interesting, my machine bombs out (not a segfault, just an invalid
operation) when trying to do glUseProgram.  I'd suspect that something
is failing during compilation and you just aren't retrieving a
compilation error message to see the failure?  Don't have time to track
it down this morning (already late for meeting).  (Tested on an Ubuntu
9.04 64-bit with AMD Radeon, btw).

Good luck,
Mike
