Did I say this before?  I would suggest that numpy develops a way
where all the SSE binary variations would be installed, and the
appropriate ones be loaded at runtime, depending on the user's CPU
capabilities.  This would also allow py2exe'd distributions to include
them all.

I would have tried wheels for windows, python 3.3 or 3.4, but there 
aren't any.
