Do you observe the sample problems simply by importing scipy, without
graph-tool? For instance:
 
    >>> import scipy
    >>> import scipy.stats
 
If you observe the same problem, then clearly the problem would be with
scipy. You should try simply re-installing it.
 
If you still have the same problems afterwards, I suggest you contact
the macports maintainers, and report a bug:
 
    https://trac.macports.org/auth/login/?next=/newticket
 
Best,
Tiago
