title: pyplot while using X11 forwarding
body: <p>I'm trying to setup my remote working environment so that I can use <code>matplotlib.pyplot</code> under ipython. My local machine and remote machine are both MAC OSX Mavericks.

Tried to install <code>pygtk</code> but can't manage to install a dependency <code>py2cairo</code> (seems to be an <a href="https://github.com/Homebrew/homebrew/issues/27485" rel="nofollow">open issue</a>). Any other thoughts? Thanks.</p>
