title: How to install virtualenv scripts to /usr/bin
body: <p>I install virtualenv with command <code>sudo /usr/bin/pip-2.6 install virtualenv</code></p>
  
  <p>And it says </p>
  
  <pre><code>Requirement already satisfied (use --upgrade to upgrade): 
  virtualenv in /usr/local/lib/python2.6/dist-packages
  Cleaning up...
  </code></pre>
  
  <p>Why pip from /usr/bin looks to /usr/local/lib?</p>
  
  <p>I need to install virtualenv scripts directly to /usr/bin, so I write </p>
  
  <pre><code>sudo /usr/bin/pip-2.6 install --install-option="--install-scripts=/usr/bin" virtualenv
  </code></pre>
  
  <p>But again it responds with</p>
  
  <pre><code>Requirement already satisfied (use --upgrade to upgrade): 
  virtualenv in /usr/local/lib/python2.6/dist-packages
  Cleaning up...
  </code></pre>
  
  <p>Adding --upgrade doesn't help.</p>
  
  <p>How can I install virtualenv scripts to /usr/bin ?</p>
