[Rock-dev] rock-ros bridging

[Sankaranarayanan Natarajan]

Hi ,

Three weeks ago i tried ROCK-ROS bridging component. Everything worked 
fine. Last week i did ROCK update and just tried to run "rock-display",  
it failed. I even did a fresh rock installation.
The following things i did:
1. Include the following text in autoproj/manifest
      package_sets:
      - gitorious: rock-ros/package_set
      layout:
      - rock.ros
2. update and build
3. run roscore in a terminal
4. setup ROS_MASTER_URI and typed "rock-display" and got the following 
error:
