title: I can't install PyQt4
body: <p>I want to install PyQt4. I've tried everything that I could find: use my command line, use brew. Nothing seems to work!</p>
  
  <p>If would be really useful if someone could explain everything from step one, if necessary reinstalling python. I'm quite new to installing files from source and I'm not sure whether I'm in the correct path or have all the files needed when I tell my terminal to install pyqt4 like this:</p>
  
  <pre><code>brew install pyqt
  </code></pre>
  
  <p>Thanks in advance!</p>
