[Nix-dev] Patch for pythonPackages.numpy

Since I recently upgraded to MacOS X 10.7, I decided to reinstall Nix (1.0)
and Nixpkgs from scratch to see how it works out. I downloaded the
python branch you mentioned and added your patch for numpy. Then I typed

   nix-build -A pythonPackages.numpy ./pkgs/top-level/all-packages.nix 

This leads to a failure in building libsigsegv-2.10 (due to a failing
test), which is a dependency of gawk-4.0.0, which in turn is a
dependency of stdenv. libsigsegv 2.10 is supposed to work fine under
MacOSX 10.7, so I suppose the failure is due to the build environment
in nixpkgs.

I don't think this is related in any way at all to your patch or to
the python branch, but it's pretty effective at preventing me from
building numpy.

Well possible. Getting ATLAS right is not a trivial job.
