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.

That was discussed on the numpy list, and would be really nice, but it may also be really difficult. OS-X has built-in support for multi-architecture binaries, but Windows does not, and while selecting a particular .dll (or .pyd) to load at run-time would be fairly straightforward numpy has more than one, and then there is the whole scipy stack, and all the third-party stuff compiled against it.

I suspect this wold have to be built-in to the python importing and distutils build system to be workable. But maybe someone smarter than me will figure it out.

Some feedback from the people who did try those wheels would help. I
asked for that on the numpy list after creating them, but didn't get
much. So I haven't been in a hurry to move them over to PyPi.

Serious chicken-egg problem there....

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

Yeah we need to get those up -- SSE2 only ones would work for MOST people.
