title: PIL and jpeg decoder not available errors on mac 10.8.2
body: <p>I had PIL installed on osx using pip, but since getting the error that jpeg decoder is not available, I uninstalled PIL so that I can first install the jpeg libraries, and then reinstall PIL. However, both the following give me errors:</p>
  
  <pre><code>    sudo pip install libjpeg
  </code></pre>
  
  <p>..Could not find any downloads that satisfy the requirement libjpeg</p>
  
  <pre><code>    sudo pip install libjpeg-dev
  </code></pre>
  
  <p>Could not find any downloads that satisfy the requirement libjpeg-dev</p>
  
  <p>Any ideas how to install the jpeg lib? Thanks.
