BUG: Install doesn't support merged setuptools+distribute
Installing from source requires distribute (0.6). In 2013, setuptools and distribute were merged into setuptools 2.1+ : http://pythonhosted.org/setuptools/merge.html

Attemping to install with setuptools 2.1 results in error "global name pkg_resources not found"

Pandas should be installable with setuptools 2.1+
