mesa-demos: no graphical window, no error, no exit

[Anton Shterenlikht]

I'm trying to set up Mesa on ia64 -current.
I've built graphics/mesa-demos as a check.
HOwever, none of the mesa-demos executables
do anything, i.e. any command sits indefinitely
seemingly doing nothing:

$ glxgears

# ps ax|grep glxgears
 3485  0  I+       0:00.04 glxgears


In the end I have to terminate with CTRL/C.

What could be the problem?

Thanks

Anton
