title: Installing specific package version with pip
body: <p>I am trying to install version 1.2.2 of <code>MySQL_python</code>, using a fresh virtualenv created with the <code>--no-site-packages</code> option. The current version shown in PyPi is <a href="http://pypi.python.org/pypi/MySQL-python/1.2.3" rel="noreferrer">1.2.3</a>. Is there a way to install the older version? I have tried:</p>
  <pre class="lang-sh prettyprint-override"><code>pip install MySQL_python==1.2.2
  </code></pre>
  <p>However, when installed, it still shows <code>MySQL_python-1.2.3-py2.6.egg-info</code> in the site packages. Is this a problem specific to this package, or am I doing something wrong?</p>
