Can't "install numpy install" on OS X Yosemite

I can't pip install pandas

or pip install numpy

after upgrading to OS X Yosemite. Both teams have worked great before. When I ran

$ pip install numpy

the compilation process takes about 30 seconds and then I get this:

I tried updating Python, re-creating my virtualenv, rebooting my system and banging my head against the table, but no one helped. I also ran brew rm gfortran

then brew install gcc

, but it didn't help.
