title: pandas looks for scikits.statsmodels instead of statsmodels
body: <p>I have:
  statsmodels 0.5.0 (formally known as scikits.statsmodels)
  pandas 0.12.0.
  (all installed from source)</p>
  
  <p>I get this error:</p>
  
  <pre><code>  File "/home/username/.local/python27/lib/python2.7/site-packages/pandas-0.12.0-py2.7-linux-x86_64.egg/pandas/stats/ols.py", line 53, in __init__
  import scikits.statsmodels.api as sm
  ImportError: No module named scikits.statsmodels.api
  </code></pre>
  
  <p>Why is pandas still looking for scikits.statsmodels? Should I install an old version of scikits.statsmodels parallel to statsmodels 0.5.0?</p>
