On GNU/Linux systems, -lGL is a linker option which means to link in
the libGL.so shared object (i.e. shared library). Mac OS X uses some
kind of alternative framework/dylib/bundle library system which I know
very little about.

Again, I don't think Yoshi's builds on Mac OS X without some tweaking.

The ruby-opengl on RubyForge (which is still basically Yoshi's with
some added docs and a tweaked build procedure) should (I suppose) work
fine on Mac and Windows (as well as GNU/Linux, of course) after the
next mkrf release (which should be any day now). Actually, if you
install mkrf from svn, you should be able to use that ruby-opengl if
you don't mind running the rake command for each individual extension
(gl, glu, glut).
