The function aglUseFont is unsupported in Carbon/Mac OS X, according to the
Carbon docs. That's probably why you're getting a bus error (the function
pointer would be nil).
Look at
http://developer.apple.com/samplecode/Sample_Code/Graphics_3D/CGText.htm
This sample code should give you what you need. After only a cursory review
of the code, it looks to me like it basically draws a string into an
(undisplayed) NSTextView and uses that to create bitmap textures on the fly,
one for each glyph, then maps them onto quads in the GL view.
