This reminds me, I recently constructed a glut.cpp as an alternative to 
x11.cpp
for drawstuff tests and which would presumably work on any GLUT system
including OS X.  Is anybody interested?

libtool is your friend, it knows about details like this. :-)

You have to link with the C++ library.  Either add a -ldstdc++ manually, 
or use "g++"
to link instead of "gcc", which will add the library automatically.

Incidentally, I work in Apple's tools group, so can answer random 
compiler questions
with at least a little bit of authority... :-)
