Are you sure that the python executable that you are using is the
64-bit python executable that you think it is?

Hm ... Well, I think so ... It certain is 64bit, or at least:

In [1]: import platform

In [2]: platform.architecture()
Out[2]: ('64bit', '')

Should I be checking something else? 

It is a python installed via macports ...
