ImportError: No module named interface

I get an error when executing "sudo vtclient":

from isobus.ibsinterface import IBSInterface
File "/usr/local/lib/python2.7/dist-packages/isobus/ibsinterface.py", line 11, in
from can.interfaces.interface import Bus
ImportError: No module named interface

Looks like the API for python-can has changed, I'm not sure when I'll have time to look into this, in the mean time, maybe try an older version of python-can?
