python on a cray xt5, ImportError: No module named site

Hi,

Got some trouble running python on a Cray XT5 which has a reduced os on 
the compute nodes, and you're supposed to link everything statically. I 
configured the build with --disable-shared and uncommented the modules 
in Modules/Setup which made sense (nearly all of them), and built with 
Cray's compiler wrappers. I set PYTHONHOME to point to the install.

I am able to run the build fine on the login nodes but when I run on the 
compute nodes I get the error:

"ImportError: No module named site".

Full output from -v pasted below. site.py is present. I tried running 
with -S, and the got "ImportError: No module named os", again os is 
present. When I commented out the os stuff and ran with -S and just 
printed sys.path it worked.

I'm not sure what the problem is. Can any one shed some light on what's 
going on here??

Thanks
Burlen
