This snippet would look like this:
(ccl:rlet ((matrix-mode :<gl>int))
(#_glMatrixMode (ccl:%get-int-ptr matrix-mode)))

GLUT is a separate framework on OS X. I haven't done anything with it.
I was under the impression that GLUT was somehow related to the aux
stuff from the red book. Perhaps I'm wrong?
I haven't gotten anywhere near tackling fonts yet, but if you are using
Carbon rather than Cocoa, there is this rather nice example (in C):
Text is used in the demo without resorting to GLUT.
