Strange, I just installed glfw 2.6 locally and I still get the same
problem, with the first call returning 0 and the next returning 1. I
also tried manually setting the opengl version back to 2.1 using
glfwOpenWindowHint in glfw 2.7, with the same result.

I'm using LuaJIT 2.0.0-beta9 that I've checked out from git. My system
is Linux/x64 as well with a cpu that ubuntu lists as "Intel® Atom™ CPU
330 @ 1.60GHz × 4"

I'm not sure what to try at this point. I know that I have support for
glCreateShader, since I've used it before in C/glut/glew programs. Is
there some other information I could capture that might make it easier
to debug the problem?
