Did you try this:

1.)  replace the first line of gentest_sphere.py to  
"#!/usr/bin/python2.5"  (or your path to python2.5)
2.) "chmod +x gentest_sphere.py"
3.) run this:  "./gentest_sphere.py gsphere.h5"  (instead of "python2.5 
./gentest_sphere.py gsphere.h5"

It may not help. But... suspicious. You used the advertised command 
line. The program may have a bug. E.g. it uses sys.argv the incorrect way.

Best,
