Thanks very much. I'm happy to remain blissfully ignorant as to why I  
should not be using gcc-4.0, and I have now successfully built and  
installed scipy. There were quite a few warnings during building, but  
I guess that goes with the territory.

Running scipy.test() from Python also throws up a lot of errors, all  
of which are along the lines of:

     !! No test file 'test_lib.py' found for <module 'scipy.lib' from  
'...ackages/scipy/lib/__init__.pyc'>

Are these anything to worry about?
