Dear Jan,

With Ondrej's help, I've managed to find a workaround to this
problem. Rather, let me say that this issue isn't numpy's, but more of
Atlas'.

The issue you menion here happens when we link numpy against
Atlas. This now causes us to depend on the BLAS provided by Atlas
instead of the reference BLAS, i.e. we depend on libatlas.so.3 instead
of refblas3. I tried the build with plain refblas, and Ondrej and I
can confirm that this problem goes away. So, I am now patching the
build system to avoid building against Atlas (which is the right way).

However, this still doesn't explain why linking against Atlas causes a
problem, and Ondrej and I have decided to test it out and leisure, and
if necessary, file a bug against Atlas.

Thanks!

Kumar

P.S. The Atlas in Debian is soooo old now! *sigh*.
