Can't install on mac

[ericelliott]

I followed the install instructions for mac, but get the following:

$ PYTHON=python2.7 apm install hydrogen
Installing hydrogen to /Users/eric/.atom/packages ✗

> zmq@2.14.0 install /private/var/folders/4r/vxjdd9_x5gbbdq001b4ctgbh0000gn/T/apm-install-dir-1151029-24081-m9hhkx/node_modules/Hydrogen/node_modules/zmq
> node-gyp rebuild


Package libzmq was not found in the pkg-config search path.
Perhaps you should add the directory containing `libzmq.pc'
to the PKG_CONFIG_PATH environment variable

Looks to me like we also need to link zeromq...

$ brew install zeromq
Warning: zeromq-4.0.5_2 already installed, it's just not linked

Maybe a more detailed troubleshooting doc would be good. =)

Brew normally would link zeromq; I'm not sure why it didn't this time.

I forget sometimes that this repo has a wiki. Maybe it's time we start using it...

Would you mind adding an entry for this to the troubleshooting page? https://github.com/willwhitney/hydrogen/wiki/Troubleshooting

[ericelliott]

Maybe you should link to that from the install guide? =)

[willwhitney]

Good call! Link added.
