I took a new clean install of OSX 10.9.3 and installed pip, and then did
pip install pandas pip install numpy
Both installs seemed to be perfectly happ
Uninstall both numpy and pandas and try installing pandas from source.
pip uninstall numpy pip uninstall pandas git clone git://github.com/pydata/pandas.git cd pandas python setup.py install
This worked for me and I am now able to use the latest version of pandas.
