title: No module named dateutil.parser
body: <p>I'm installing Rapidpro which uses django. I'm running <code>python manage.py runserver</code></p>
  
  <p>I get an error:</p>

  <p>I have followed the steps in this post: <a href="https://stackoverflow.com/questions/20853474/importerror-no-module-named-dateutil-parser">ImportError: No module named dateutil.parser</a>, but to no avail! (Both untaring and using pip)</p>
  
  <p>I'm a complete python noob, so it's quite possible I'm overlooking something obvious. I'm installing on Ubuntu 15.04.</p>
  
  <p>Ideas? Thanks!</p>
