Hi all,
I'm having some trouble pickling shapely geometry objects. After
saving a shapely geometry object in my beaker session (which pickles
the object, I am unable to reload it from the database) This is the
error I'm getting:
>>> import cPickle
>>>

I wanted to check to see if it was just fixed in trunk, but I'm unable
to run trunk because util seems to have disappeared:
