This is trying to use ATLAS, do you have that installed? I'd expect all
those source builds to use Accelerate.

Can you:
- give us the full build command you used
- put the complete build log in a gist and link to it
- check that ``python -c "import numpy; numpy.test('full')`` passes

I've been using Homebrew and gfortran 4.9.1 for a year or so without issues.
