I'm actually surprised that this is necessary.  I was under the 
impression that the distutils pick reasonable defaults simply based on 
the python that is running.  In your case,  I would expect numarray to 
install to /usr/local/lib/pythonX.Y/site-packages without specifying any 
prefix.  What happens on SuSE?

In numarray, this is spelled:

 >>> import numinclude
 >>> numinclude.version
'0.3.4'

I'll add __version__ to numarray as a synonym.
