Your environment is not setup correctly for building native modules. Please do some more googled and reading of readme files.

I hope I'm not re-opening this by commenting. @activexJ In case you haven't resolved this yet, I fixed this by removing the Python installed in my Library Frameworks folder. Somewhere in the transition between Mavericks, Yosemite and El Capitan it was left there and the system set that as its default directory. Had to remove it, install Python via Brew, then fix some symlinks with it. My issue with installing it may not be the same for you, but I would start there.

@defunctzombie would it help if sometime down the road we compile the better-known solutions into a help file so that tickets like these are slowed down? I see another ticket or two recently created that can easily be solved with something like that -- though the persons should be searching via Google anyways for a solution
