title: Permission Denied on httplib2 install
body: <p>I'm trying to install the httplib2 library for Python so I can use it to interact with the Twitter but I get the following error in the console when I try to install via 'python setup.py install'. </p>
  
  <p>This is a new MBA and I am the only user (and Admin) so I shouldn't get denied so rudely!</p>
  
  <pre><code>error: could not create '/Library/Python/2.7/site-packages/httplib2': Permission denied
  </code></pre>
  
  <p>Thoughts?</p>
