title: Using gcc not llvm-gcc with Mac OS X Lion
body: <p><code>gcc</code> is symbolically linked to <code>llvm-gcc</code> on Mac OS X Lion.</p>
  
  <pre><code>prosseek ~&gt; ls -alF /usr/bin/gcc
  lrwxr-xr-x  1 root  wheel  12 Nov 12 14:39 /usr/bin/gcc@ -&gt; llvm-gcc-4.2
  </code></pre>
  
  <p>How can I setup to use <code>gcc-4.2</code> when <code>gcc</code> is called?</p>
