title: Django: 'current_tags' is not a valid tag library
body: <p>I have a small Django project I received from a friend. The code works perfectly on his system. However, on my system I get the following error message when running the server:</p>
  <blockquote>
  <p><strong>TemplateSyntaxError at /</strong></p>
  <p>'current_tags' is not a valid tag library: Template library current_tags not found, tried django.templatetags.current_tags</p>
  </blockquote>
  <p>The problem is with a line in an html file:</p>
  <pre><code>{% load current_tags %}
  </code></pre>
  <p>This exact same code works on his system with no errors. What could that be?</p>
