title: "ImportError: No module named httplib2" even after installation
body: <p>I'm having a hard time understanding why I get <code>ImportError: No module named httplib2</code> after making sure httplib2 <em>is</em> installed. See below:</p>
  
  <pre><code>$ which -a python
  /usr/bin/python
  /usr/local/bin/python 
  
  $ pip -V
  pip 1.4.1 from /usr/local/lib/python2.7/site-packages/pip-1.4.1-py2.7.egg (python 2.7
  
  $ pip list
  google-api-python-client (1.2)
  httplib2 (0.8)
  pip (1.4.1)
  pudb (2013.5.1)
  Pygments (1.6)
  setuptools (1.3.2)
  wsgiref (0.1.2)
  
  $ pip install httplib2
  Requirement already satisfied (use --upgrade to upgrade): httplib2 in /usr/local/lib/python2.7/site-packages
  Cleaning up...
