title: How to tell Homebrew to install inside virtualenv?
body: <p>Here's my problem. I can't install MatPlotLib both via <code>pip</code> and from source (<a href="https://stackoverflow.com/questions/25700400/matplotlib-installation-on-mavericks">Matplotlib installation on Mavericks</a>). I tried <code>brew install matplotlib</code> and the installation successfully ended. However, it installed MatPlotLib globally and not inside the currently activated VirtualEnv. </p>
  
  <p>Is it possible to tell brew to install a package inside the current VirtualEnv?</p>
