Nils,

I compiled ATLAS by myself on that computer. ATLAS detects whether to
use SSE or not during the build. Of course you have to compile/link
numpy and scipy (or only numpy?) against this ATLAS.

Ed Schofield uploaded precompiles ATLAS binaries to
http://www.scipy.org/Installing_SciPy/Windows

This may save some time...

BTW, isn't there any way to dynamically link against the ATLAS library?
