I am sure the thing that stopped me was not being able to call NSApplicationInit()... I did manage to get something going but it kept dropping out with an error, which, on looking it up said I had to call NSApplicationInit() but my CFFI experience is limited and I couldn't work out how to do it.
I looked at Verrazano as well but in the end time pressures made me go for X11. It just worked, I had to make a small change to get it to work on an intel mac though if I remember I just modded the library.lisp file a bit. My finally chaotic glut def looks like:
(define-foreign-library glut
;;-- (sjc-03-jul-06) -- added this line to ensure my locally built
;;-- OpenGLUT library is loaded as the "glut" library!
;;
;; (1) /usr/local/lib/libopenglut.dylib => my build from OpenGLUT source package.
;; (2) /sw/lib/libglut.dylib => FINK installation of 3.7-1025
;;
;; Q. Which one is 'better' to use, if any ?!
;; (1) because (2) doesn't have glutLeaveMainLoop etc !!!
;;
;((:and :darwin :x86) "/sw/lib/libglut.dylib")
((:and :darwin :x86) "/usr/local/lib/libopenglut.dylib")
;((:and :darwin :x86) (:framework "GLUT"))
;(:darwin (:or "libglut.dylib" "libglut.3.dylib" #-(and)(:framework "GLUT")))
(:windows "freeglut.dll") ; XXX: is this right?
(:unix (:or "libglut.so" "libglut.so.3")))
which, removing the chaff leaves this, I added the :x86 to make it intel friendly!
(define-foreign-library glut
((:and :darwin :x86) "/usr/local/lib/libopenglut.dylib")
(:windows "freeglut.dll") ; XXX: is this right?
(:unix (:or "libglut.so" "libglut.so.3")))

Yeah, it annoys me a lot. I'll check if anyone has any prior work done in that direction first, but if not, I'll look into it. The problem is I have little cocoa/carbon experience. Time to learn I guess.

That GLUT will call exit() (and kill your Lisp) very often, doesn't
that annoy you? Hey, you could port freeglut to Cocoa (or is it
Carbon?), that'd be nice. :-)
