Tracked down a solution here:

https://github.com/zeromq/pyzmq/issues/493

Something had gone wrong with the install of pyzmq but uninstalling via macports or pip then reinstalling didn't get rid of the problem files.

Deleting the zmq directories from /Library/Python/2.7/site-packages/ then reinstalling using pip fixed this.
