Using Kubuntu 12.04, Kernel 3.2.0-40-generic, installed ROS Groovy ros_comm version 1.9.44. I've tried several times to install Groovy into a VMware Image and on a pure machine. Trying to start the catkin build in Eclipse Juno (started from a bash window), i've got:

Does anybody know why? (I never programmed python)

I think you need to add the PYTHONPATH variable to eclipse. Project > Properties > C/C++ Build > Environment

The value should be /opt/ros/hydro/lib/python2.7/dist-packages. Can use "export | grep PYTHONPATH" to check your value.

Worked for me as well on Ubuntu 14.04 and ROS Indigo, thanks!
