[SciPy-user] dfftf1.f:0: error: CPU you selected does not support x86-64 instruction set

Hi.

  I'm trying to install scipy, and have run into what is probably a 
simple problem.  I think I've successfully built numpy (as well as blas, 
lapack, fftw, etc.), but  run into the following error after running 
python setup.py build:

Looking through past posts to this group, this error seems similar to a 
previous issue posted where the Core2 processor wasn't properly being 
identified.  I'm running CentOS 5 on a  system with two Xeon 5400 series 
chips.  Just in case this issue had been recently fixed, I downloaded 
the latest scipy from the svn today, but had the same problem.

Just in case this is helpful, here is my /proc/cpuinfo:

Then similar information is repeated 7 more times, with processor going

Thanks for any help.
