David,
One more thing. I checked to see if the SciPy libraries had
dependencies on ATLAS. They do not, however, the eigenvector
calculation is still much faster than Numeric?
This is very strange.

Hi David,
Yes, when Numeric compiles it does look like the linking is being
done properly. I captured the build to a file and see a few lines
similar to:
gcc -pthread -shared build/temp.linux-i686-2.4/Src/lapack_litemodule.o
-L/d2/lib/atlas -llapack -lptcblas -lptf77blas -latlas -lg2c -o

Hi John,
I do have more than one version of Python laying around.
To do the build and install I am typing:
/d2/python/bin/python setup.by build > &! build.out
/d2/python/bin/python setup.by install > &! install.out
Should I be doing something different?

Hi David,
I performed the above check, and sure enough, Numeric
is --not-- linked to the ATLAS libraries.
I followed each of your steps outlined above, and Numeric
still is not linking to the ATLAS libraries.
My setup.py file is attached below.
Thanks ,
