title: GCC does not work under Anaconda and Virtualenv
body: <p>I am trying to install a python packages that uses <code>gcc</code> to compile it. I can install it using <code>sudo</code> but not under a <code>VirtualEnv</code> or under <code>Anaconda</code>. I am trying to install it using <code>pip</code>. The error that I get is:</p>
  
  <blockquote>
    <p>error: command 'gcc' failed with exit status 1</p>
  </blockquote>
  
  <p>Googling it I found that the usual solution is to install <code>python-dev</code> but I already have it installed.I am using Ubuntu 12.10 64 bits.</p>
  
  <p>Any clues on this?</p>
