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.

I really think that's our best near term workaround - still room for improvement, but " pip install numpy assumes SSE2" is a much better situation than "pip install numpy doesn't work on Windows". Such a change would help a lot of people *right now*, while still leaving room to eventually figure out something more sophisticated (like postinstall hooks or simpler runtime multi-build support or NumPy changing to a dependency that internally makes this decision at runtime).
