rdfextras uses pyparsing but does not depend on it.
When using SuRF's example with rdflib/rdfextras the follow exception is raised:

$ python

>>> from surf import *

>>>
>>> store = Store( reader='rdflib',
... writer='rdflib',
... rdflib_store = 'IOMemory')
>>>
>>> session = Session(store)
>>>
>>> print 'Load RDF data'

>>> store.load_triples(source='http://www.w3.org/People/Berners-Lee/card.rdf')
True

Doing an `easy_install pyparsing` solves the issue.
