import in rosgraph/masterapi.py failing

edit

Hi,

I am getting an error in the rosgraph/masterapi.py file.

I am trying to run the turtlebot_arm_bringup arm.launch from answer17 and am also using their arbotix package. I am using these packages as they appear to provide support for the pincher arm I am using.

I am using Indigo on Ubuntu 14.04, with Python 2.7.6.

The error I get is:

$ roslaunch turtlebot_arm_bringup arm.launch 

Traceback (most recent call last):

from xmlrpclib import ServerProxy  # Python 2.x
ImportError: cannot import name ServerProxy

So it looks like python can find xmlrpclib.py (so don't think it's a PYTHONPATH issue) but I'm not sure why it can't import ServerProxy (it exists in this file). Any ideas on what is going wrong?
