title: Install particular version with easy_install
body: <p>I'm trying to install <code>lxml</code>. I've had a look at the website, and version 2.2.8 looked reasonable to me but when I did <code>easy_install lxml</code>, it installed version 2.3.beta1 which is not really what I want I presume.</p>
  
  <p>What is the best way to fix this and how can I force easy_install to install a particular version?</p>
