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.
