import error "pandas/hashtable.so: Symbol not found: _get_c_string"
I apparently successfully installed pandas using pip (there were a large number of warnings generated), but when I import pandas I get:

dlopen(/Ureka/1.0beta5/Ureka/variants/scipy2013/lib/python2.7/site-packages/pandas/hashtable.so, 2): Symbol not found: _get_c_string

I'm using Mac OSX 10.8.4 with the latest version of Xcode (Version 4.6.3 (4H1503)), Python 2.7.3 and numpy 1.6.2.

Please let me know if there's any more information I can provide.

Many thanks,

Emma :)
