title: Symbol not found: ___sincos_stret
body: <p>I've recently installed root on a system running Mac OS X 10.8</p>
  
  <p>In pasting the error on StackOverflow, I've replaced my home folder title with a <code>xyzzy</code> to protect my name.</p>
  
  <p>When attempting to <code>import ROOT</code> while in a python interactive mode, I get:</p>
  
  <pre><code>Traceback (most recent call last):
    File "&lt;stdin&gt;", line 1, in &lt;module&gt;

  import libPyROOT as _root
  ImportError: dlopen(/Users/xyzzy/Documents/Code/root/lib/libPyROOT.so, 2):

  </code></pre>
  
  <p>Does anyone know what could be causing this error? ROOT was installed with MacPorts. </p>
