This sounds like the problem due to ghci not running as a Mac App.  If 
it is, the solution *used* to be to use the "EnableGUI" module and fix 
described on the SOE page http://www.haskell.org/soe/software1.htm; 
using this, I was able to run glut programs from ghci under OSX.

However, I've just tried running a program that uses Glut from ghci, and 
even with the EnableGUI module, I now also get the behaviour that Conal 
describes.   I upgraded my version of HOpenGL and Glut around two months 
ago, so wonder if something has changed?
