title: Why am I getting the error: command 'llvm-gcc-4.2' failed with exit status 1
body: <p>I am setting up os X 10.7.</p>
  
  <p>I am using the default install of Python:<br>
  /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/  </p>
  
  <p>I use a Python based package manager called easy_install. 
  Easy_install seems to not be able to find the compiler.</p>
  
  <p>EDIT: When I tried to install  MySQL-python I got this error:  </p>

  <p>Xcode 4.1 used GCC, but with Xcode 4.2 that seems to have changed.</p>
  
  <p>What compiler does Apple want us to use?
  How do I setup the configuration so I can compile OSS?</p>
