In case some numbers help: the numerical community has been tracking the deployment of SSE2 to decide when to switch over for numpy/scipy builds, and at this point what I hear is: - ~0.5% of Firefox crashes are on machines that are missing SSE2 - <0.1% of machines with Steam installed are missing SSE2 I'm not sure what python distributions like Anaconda or Activestate are doing wrt SSE2, but even if their builds do require SSE2 then their build tooling might provide a quick way to generate a whole installable environment with custom build options for targeting older systems. (Continuum as of today still hasn't released build scripts for the bottom of their stack -- python/numpy/etc. -- but they've claimed willingness to do so and there's increasing calls to make a "centos" version of Anaconda. And all the tooling beyond that -- e.g. the actual package manager -- is FOSS.) -n
