Thank you. Did that, and NumPy compiled with a Brazillion warnings, but
no errors. 

Then I did:
export LD_RUN_PATH=/opt/lib:/opt/intel/cc/9.1.042/lib:/opt/intel/mkl/8.1/lib/32
(because I used the Intel defaults, and those are the correct paths)

But since the SUSE NumPy rpm is also installed, how do I determine
which version is loaded when the command:
from numpy import *
is issued in python? Subjectively, it appears the new version is not
being used. I expect a significant speed difference using the Intel
compiler and MKL on a Core 2 Duo.

Why is this so difficult?

Thanks,
