title: Different versions of python-requests on identical systems
body: <p>I have two VMs, both running Ubuntu 12.04.3 LTS</p>
  
  <pre><code> $ cat /etc/issue
   Ubuntu 12.04.3 LTS \n \l
  </code></pre>
  
  <p>And I have installed python-requests through apt-get on both systems. However, on one VM I have version 1.2.3 and the other 0.8.2..</p>
  
  <pre><code>&gt;&gt;&gt; requests.__file__
  '/usr/local/lib/python2.7/dist-packages/requests/__init__.pyc'
  &gt;&gt;&gt; requests.__version__
  '1.2.3'
  </code></pre>
  
  <p>The other system:</p>
  
  <pre><code>&gt;&gt;&gt; requests.__file__
  '/usr/lib/python2.7/dist-packages/requests/__init__.pyc'
  &gt;&gt;&gt; requests.__version__
  '0.8.2'
  </code></pre>
  
  <p>How can this be? What might I have done that caused this?</p>
  
  <p>I can see that the <strong>file</strong> indicates that the newer version is located in /usr/local, can that give any hint of the problem?</p>
