I have the academic distribution of EPD 7.1 for MacOS 10.6.x, which has pandas 0.3 version. The latest official version is 0.5.0 so I though I would upgrade to the latest.
Here is what I did:
- saved the
zipfile of the source from here - executed
sudo python setup.py install - ran tests by executing
nosetests pandas
Please keep in mind I am a total newbie to python. Any insights on why my install failed would be greatly appreciated. Below is a snippet of the errors. The entire log can be found at Error log
Results:
Ran 1498 tests in 55.011s FAILED (SKIP=4, errors=91, failures=14)

@wesm - thanks for your quick reply. Next time I will definitely use the mailing list. So I actually backtracked... installed the official 0.5.0 release and compiled from source. I received 3 errors (see below). I did not experience any problems running sudo python setup.py install

Best place to ask this question would be on the mailing list (luckily Google Alerts let me know about this right away!). It looks like your install failed and it's still using pandas 0.3.0. Were there any errors when you ran python setup.py install? You may have to upgrade your Cython installation if you're building from a git snapshot (sudo easy_install -U Cython). If that doesn't work, try nuking your existing pandas install:
sudo rm -rf /Library/Frameworks/EPD64.framework/Versions/7.1/lib/python2.7/site-packages/pandas
and reinstalling. The tarball on PyPI includes pre-built Cython sources. If you're building from source anyway I recommend building from the head revision on git anyway. I'm days away from releasing pandas 0.6.0.

The problem was resolved by:
1) installing the pandas 0.6.0 release which Wes made available November 25/2011.
2) removing the existing scikits package, which is bundled with EPD 7.1 (version 0.2) and installing the latest release using 'easy_install -U scikits.statsmodels'.
The above were suggestions made by Wes and folks on the pystatsmodel mailing list (thank you to all).
