noticing freeglut vs not

I'm looking for a way to use MainLoopReturns when freeglut is present and
not when it isn't.  I could use some help.  I figure that the implementation
has some way to generate that error message, and maybe we could similarly
just do a standard ungraceful exit if freeglut is missing.

The great thing about MainLoopReturns is that it plays nicely with ghci.
Closing a window returns to ghci for more fun.

Some more info at http://trac.haskell.org/FieldTrip/ticket/8 .

Any ideas?

Thanks,  - Conal
