Regarding my problems raytracing on my debian/testing machine.

The system has 128mb of ram.

I have attached a pymol session file.  To generate the session file, I
loaded a very simple molecule into pymol.  After loading the session file 
and executing the ray command I get a segmentation fault.  The tail end
of pymols output to the shell is show below.  As you can see below, while 
pymol starts up I recieve an error complaining about 'PYMOL_PATH'.  I
don't know if this error is related to the problems I am having with ray
tracing.  Please let me know if you would like any more information.
