Try ssh -Y instead of ssh -X

I'm having some trouble with OpenGL over X11. A professor asked me
to look into this for him, and I'm stumped. What he wants to do is
to run an OpenGL app on a Linux machine on his Mac over X. He's
got X11 installed, and he can run other applications (like Firefox
or Eclipse) over X just fine. When he tries to run an OpenGL app,
connecting with "ssh -X user@host" he gets the message "freeglut (./
rectangle): OpenGL GLX extension not supported by display
'localhost:10.0'". Using a regular terminal, connecting with the
same command, he gets the message "freeglut (./rectangle): failed
to open display ''". Connecting from a Linux machine to this Linux
machine, the application runs fine. Using X11, $DISPLAY on the
Linux machine is set to localhost:10.0, and using a normal terminal
$DISPLAY is not set.
The app compiles fine on both Linux and Mac, although with
different linker flags, and runs fine on the local machine. I've
tried it on my Mac and I get the same results. We're also both
running the same software versions. Mac OS X 10.4.3. XFree86 4.4.0
release 6600. All available updates have been applied. I've got
an ATI Radeon 9200 graphics processor with AGP 4X support, 32MB
dedicated DDR video memory.
Linux linker flags:
-L/usr/X11R6/lib -L/usr/local/lib -lGL -lGLU -lm -lglut
Mac linker flags:
-L/usr/local/lib -lm -framework Cocoa -framework OpenGL -framework
GLUT -framework Foundation -lstdc++
So, with that out of the way, here's my question. With this setup,
is it possible to use X11 to connect to a Linux machine, run an
OpenGL app compiled on the Linux machine, and have the display
forwarded to the Mac? Is there anything that can be done (config
changes, installing packages, etc.) to get this to work?
