[lens-starter] npm start fails

[pkra]

A fresh clone of lens-starter (or AMS-lens) fails to npm start right now. I'm guessing some dependencies have changed?

$ npm start

> lens-starter@2.0.0 start /tmp/lens-starter
> node server.js

events.js:154
      throw er; // Unhandled 'error' event
      ^

Luckily, I'm just stupid. Sorry for the noise. I had another server running on a different console..
