title: How to import and use python Levenshtein extension on OSX?
body: <p>I've downloaded the python-Levenshtein archive and extracted Levenshtein dir. So, in result I have the following files structure:</p>
  
  <pre><code>Levenshtein
    - __init__.py
    - _levenshtein.c
    - _levenshtein.h
    - StringMatcher.py
  myscript.py
  </code></pre>
  
  <p>And the following <code>myscript.py</code> content:</p>
  
  <pre><code>from Levenshtein import *
  from warnings import warn
  
  print Levenshtein.distance(string1, string2)
  </code></pre>
  
  <p>But I get the following error - </p>
  
  <pre><code>Traceback (most recent call last):
    File "myscript.py", line 1, in &lt;module&gt;
      from Levenshtein import *
    File "/path/to/myscript/Levenshtein/__init__.py", line 1, in &lt;module&gt;
      from Levenshtein import _levenshtein
  ImportError: cannot import name _levenshtein
  </code></pre>
  
  <p>What is wrong here? </p>
