title: Import Numpypy when using pypy2.2
body: <p>I used to have pypy verion 1.9. I could do the following to import numpypy:</p>
  
  <pre><code>&gt;pypy
  Python 2.7.2 (341e1e3821ff, Jun 07 2012, 15:42:54)
  [PyPy 1.9.0 with GCC 4.2.1] on darwin
  Type "help", "copyright", "credits" or "license" for more information.
  And now for something completely different: ``translating pypy with cpython is
  soooooo slow''
  &gt;&gt;&gt;&gt; import numpypy
  </code></pre>
  
  <p>Recently I updated my os and installed pypy Version 2.2 now I am not able to import numpypy</p>
  
  <pre><code>&gt;&gt;&gt;&gt; import numpypy
  Traceback (most recent call last):
    File "&lt;stdin&gt;", line 1, in &lt;module&gt;
  ImportError: No module named numpypy
  </code></pre>
  
  <p>What could be the issue? I know numpy is not fully supported, but I have many scripts that use the limited functionality of numpypy in pypy.</p>
