title: Problems Installing Python Imaging Library (PIL)
body: <p>I'm trying to install Python Imaging Library,
  Running on Mac OS X 10.6.8
  Python version 2.6</p>
  
  <p>Everything went well until I ran </p>
  
  <pre><code>python setup.py build_ext -i
  </code></pre>
  
  <p>I get the following error on Terminal</p>
  
  <pre><code>unable to execute gcc-4.2: No such file or directory
  error: command 'gcc-4.2' failed with exit status 1
  </code></pre>
  
  <p>-- Could you please advice if I need to install some other library prior to running this installation? ---  many thanks</p>
