Ros install on OSX help?

edit

I am trying to install ROS on my Mac. Using the instructions provided for the mac homebrew installation (obviously). I get through to step 3.1 and then get hung up on running cmake step. The configuration however does not finish. I get several warnings but only one error. Here is my report. -- +++ catkin -- Found gtest: gtests will be built.
