title: pip cannot uninstall <package>: "It is a distutils installed project"
body: <p>I tried to install the Twilio module:</p>
  
  <pre><code>sudo -H pip install twilio
  </code></pre>
  
  <p>And I got this error:</p>
  
  <pre><code>Installing collected packages: pyOpenSSL
    Found existing installation: pyOpenSSL 0.13.1
  Cannot uninstall 'pyOpenSSL'. It is a distutils installed project and             
  thus we cannot accurately determine which files belong to it which 
  would lead to only a partial uninstall.
  </code></pre>
  
  <p>Anyone know how to uninstall pyOpenSSL?</p>
