ray: Macbook installation error

Hi, I’m following the instructions to install Ray on a macbook - http://ray.readthedocs.io/en/latest/install-on-macosx.html#installation-on-mac-os-x.

So far I installed the dependencies successfully. But when I try to install Ray using ‘python setup.py install --user’, I’m getting build failures.
