title: How to fix Python Numpy/Pandas installation?
body: <p>I would like to install Python Pandas library (0.8.1) on Mac OS X 10.6.8. This library needs Numpy>=1.6.</p>
  
  <p>I tried this</p>
  
  <pre><code>$ sudo easy_install pandas
  Searching for pandas
  Reading http://pypi.python.org/simple/pandas/
  Reading http://pandas.pydata.org
  Reading http://pandas.sourceforge.net
  Best match: pandas 0.8.1
  Downloading http://pypi.python.org/packages/source/p/pandas/pandas-0.8.1.zip#md5=d2c5c5bea971cd760b0ae6f6850fcb74
  Processing pandas-0.8.1.zip
  Running pandas-0.8.1/setup.py -q bdist_egg --dist-dir /tmp/easy_install-ckAMym/pandas-0.8.1/egg-dist-tmp-0mlL7t
  error: Setup script exited with pandas requires NumPy &gt;= 1.6 due to datetime64 dependency
  </code></pre>
  
  <p>So I tried to install Numpy</p>
  
  <pre><code>$ sudo easy_install numpy
  Searching for numpy
  Best match: numpy 1.6.2
  Adding numpy 1.6.2 to easy-install.pth file
  
  Using /Library/Python/2.6/site-packages
  Processing dependencies for numpy
  Finished processing dependencies for numpy
  </code></pre>
  
  <p>So I tried again</p>
  
  <pre><code>$ sudo easy_install pandas
  </code></pre>
  
  <p>But the problem is still the same !</p>
  
  <pre><code>error: Setup script exited with pandas requires NumPy &gt;= 1.6 due to datetime64 dependency
  </code></pre>
  
  <p>I run Python </p>
  
  <pre><code>$ python
  Python 2.6.1 (r261:67515, Jun 24 2010, 21:47:49) 
  [GCC 4.2.1 (Apple Inc. build 5646)] on darwin
  Type "help", "copyright", "credits" or "license" for more information.
  &gt;&gt;&gt; import numpy as np
  &gt;&gt;&gt; np.__version__
  '1.2.1'
  </code></pre>
  
  <p>So Numpy 1.6 doesn't seems to be installed correctly !</p>
  
  <p>I tried to install Numpy 1.6 with <code>pip</code> (instead of <code>easy_install</code>)...</p>
  
  <pre><code>$ sudo pip install numpy
  Requirement already satisfied (use --upgrade to upgrade): numpy in /Library/Python/2.6/site-packages
  Cleaning up...
  </code></pre>
  
  <p>I added <code>--upgrade</code> flag</p>
  
  <pre><code>$ sudo pip install numpy --upgrade
  Requirement already up-to-date: numpy in /Library/Python/2.6/site-packages
  Cleaning up...
  
  $ sudo pip install pandas
  Downloading/unpacking pandas
    Downloading pandas-0.8.1.zip (1.9MB): 1.9MB downloaded
    Running setup.py egg_info for package pandas
      pandas requires NumPy &gt;= 1.6 due to datetime64 dependency
      Complete output from command python setup.py egg_info:
      pandas requires NumPy &gt;= 1.6 due to datetime64 dependency
  
  ----------------------------------------
  Command python setup.py egg_info failed with error code 1 in /tmp/pip-build/pandas

  </code></pre>
  
  <p>I also tried to install binary version of Numpy <a href="http://sourceforge.net/projects/numpy/files/" rel="noreferrer">http://sourceforge.net/projects/numpy/files/</a>
  numpy-1.6.2-py2.6-python.org-macosx10.3.dmg but it fails !!! (installer said me that numpy 1.6.2 can't be install on this disk. Numpy requires python.org Python 2.6 to install.</p>
