Comment:

 I think this notice should not be displayed in the installer, because it's
 only relevant for a tiny fraction of users. How about adding a
 PACKAGERS.txt file?

 Checking what it was compiled with should be easy to add, the problem is
 what to compare it with? I don't think the numpy.distutils.cpuinfo is
 completely reliable, so failing on import could go very wrong. For
 example, for my Core2Duo CPU:
 {{{
 >>> cpu.has_sse()
 False
 >>> cpu.has_sse2()
 True
 >>> cpu.has_sse3()
 }}}
 I'm pretty sure it does understand SSE3 (and SSE4).
