title: Development build of pandas giving importerror: C extension: 'hashtable' not built on python 3.4 (anaconda)
body: <p>Try to do a development build with 3.4 (have previously managed in 2.7). Python is just an anaconda installation on osx10.10. I can get </p>
  
  <p>I:</p>
  
  <ul>
  <li>git cloned pandas </li>
  <li>ran python setup.py build_ext --inplace (got no errors)</li>
  <li>ran python setup.py develop. </li>
  </ul>
  
  <p>But when I try and import pandas I get: </p>
  
  <pre><code>import pandas as pd
  Traceback (most recent call last):
  
    File "&lt;ipython-input-2-af55e7023913&gt;", line 1, in &lt;module&gt;
      import pandas as pd
  
    File "/Users/Nick/github/pandas/pandas/__init__.py", line 13, in &lt;module&gt;
      "extensions first.".format(module))
  
  ImportError: C extension: 'hashtable' not built. If you want to import pandas from the source directory, you may need to run 'python setup.py build_ext --inplace' to build the C extensions first.
  </code></pre>
  
  <p>Note that when I do build_ext I get the following (apparently fine) output:</p>
  
  <pre><code>pandas(master)$python setup.py build_ext --inplace

  <p>Further, I can get pandas installed if I run <code>conda install pandas</code>, but would really like a development environment for code development. </p>
