title: libxml2.2.dylib reference in python program
body: <p>A python library that I'm using uses libxml2.2.dylib.  I'm getting this error message:</p>
  
  <p>Reason: </p>
  
  <pre><code>Incompatible library version: etree.so requires version 12.0.0 or later, but libxml2.2.dylib provides version 10.0.0
  </code></pre>
  
  <p>My system's version of <code>libxml2.2.dylib</code> is older and is in <code>/usr/lib/</code>.  I downloaded the newest version of libxml2.2.dylib using homebrew, and that is in <code>/usr/local/Cellar/libxml2/2.9.1/lib/</code>.</p>
  
  <p>I would like my Python application to use that version instead of the one the system uses.  </p>
  
  <p>Is this a matter of adding the homebrew folder to the path?</p>
