OSX's OpenGL implementation requires a GL context to exist before you can 
create a quadric; this also applies to Linux & probably other Unixes, 
Windows happens to be different and lets you create a quadric any time.

So, if you move your gluNewQuadric() call to happen _after_ you've opened 
a window (for instance, after calling glutCreateWindow), then it should be 
fine, and you'll only need to create it once.
