Hi,
Good, then you should try the patch for Ticket 991 :
http://projects.scipy.org/numpy/ticket/991.

Note that Python 2.6 documentation says:
"It can handle ZIP files that use the ZIP64 extensions (that is ZIP 
files that are more than 4 GByte in size). "

This is better than the Python 2.5.2 documentation. So can you try 
Python 2.6 ?

It would be great to resolve your numpy issue especially for other users 
- at least to say whether or not the patch or a new Python solves it.
