title: python pip install psycopg2 install error
body: <p>I did a simple <code>pip install psycopg2</code> on mac system. It installed fine, but when I try to use psycopg2 I get the error:</p>
  
  <pre><code>Reason: Incompatible library version: _psycopg.so requires version 1.0.0 or later, but libssl.0.9.8.dylib provides version 0.9.8
  </code></pre>
  
  <p><code>pip freeze</code> shows <code>psycopg2==2.4.5</code> just right. I have installed psycopg2 on several virtualenvs but this is the first time I am seeing such error. I tried uninstalling and reinstalling, same results. Please help</p>
