I suspect the problem is that I was using an Athlon chip without SSE2 to
build binaries in the past. That machine is now being used by my kids
and my environment on it has been "messed-up"
There may also be a problem with using the Microsoft compiler to build
NumPy (and then calling out to ATLAS which was built with a different
compiler). Issues like this have happened in the past. And, the most
recent binaries of NumPy were built with the Microsoft compiler.
