Yeah, due to various infelicities in the distutils stack, automated dependency installation when building stuff is pretty wonky, and a lot of things need numpy to be installed before you try building them. So doing 'pip install numpy' first is a good idea before trying to install any of the rest of the numerical stack.

Thanks to Matthew Brett's tireless efforts (hat tip to Zhang Xianyi for fixing a bunch of bugs in OpenBLAS just for us), there are now[1] numpy linux wheels with optimized BLAS up on PyPI, so if you have pip >= 8.1.0, then 'pip install numpy' should Just Work on linux without needing a compiler at all (and likewise on windows and osx). -n [1] now = "since ~1 hour ago" ;-) -- Nathaniel J.
