I tried your repository 
(http://software.opensuse.org/download/home:/ashigabou/openSUSE_10.2/) 
with two machines running openSUSE 10.2: 
1. AMD Athlon desktop
2. Pentium-M laptop. 

The repository works with Yast (installation program). 
The prebuilt packages work on both machines. They especially work with 
matplotlib from the http://repos.opensuse.org/science/ repository. (I 
didn't try timers and testers.)

Building Atlas succeeds on the Pentium-M (2). On the Athlon (1) the 
sanity checks fail. 

The resulting Atlas RPM is missing two links:
/usr/lib/atlas/sse2/libblas.so.3   -> /usr/lib/atlas/sse2/libblas.so.3.0
/usr/lib/atlas/sse2/liblapack.so.3 -> /usr/lib/atlas/sse2/liblapack.so.3.0

When I try your one line examples, I see a nine times speedup with 
Atlas.

Thank you for your efforts! You provide an easy way to install Atlas 
on Suse for the first time.

Regards,
Eike.

PS.: 
I still think you should contribute to the 
http://repos.opensuse.org/science/ repository. Then this quite 
comprehensive repository would get decent Blas and Atlas too.
