Node ZeroMQ Bindings Fail to Recompile

[ElliotChong]

When attempting to require the zmq module I'm receiving a repeated error (pasted below). I'm guessing this has something to do with the way the zmq module handles its particular build process; however, I figured I'd check here if someone has any pointers for debugging, avenues for investigation, or suggestions on fixes.

I'm using Electron 1.3.8 to load require-rebuild on OSX 10.11.6 - The module was originally installed and built with Node v6.9.1.

Thanks!
