title: Django Tutorial - ImproperlyConfigured exception (pytz isn't installed)
body: <p>I'm currently working through the official Django tutorial using version 1.6.1 and version 2.7.5 of python on OSX. I'm working on part 2, which is the admin interface. When I attempt to go to /admin/polls/poll/, I get the following error report:</p>
  
  <pre><code>ImproperlyConfigured at /admin/polls/poll/
  This query requires pytz, but it isn't installed.
  Request Method: GET

  Django Version: 1.6.1
  Exception Type: ImproperlyConfigured
  Exception Value:    
  This query requires pytz, but it isn't installed.
  Exception Location: /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/db/backends/sqlite3/base.py in datetime_trunc_sql, line 196

  <p>I attempted to install pytz by installing pip (which required installing setuptools) but this made no difference. Also, I am going through this tutorial for a second time, and I know I didn't run into this problem a month ago. Could updating to Mavericks have caused some problem?</p>
