Cant seem to "sudo npm install -g homebridge"

I’m installing on OS X El Capitan. I installed the npm and node.js from https://nodejs.org/dist/v4.2.6/node-v4.2.6.pkg

I’ve done the suggested chown commands (except the /usr/local) and even ran everything under su.

Below is the output form the install and the debug file.

$sudo npm install -g homebridge

the nam-debug.log has almost 2500 lines in it though I think the relative part is this:

I had the same issue on my RPi. This seemed to fix it for me sudo apt-get install libavahi-compat-libdnssd-dev

–unsafe-perm fixed it for me
