How to solve 'ImportError: No module named door_msgs.msg' ?

edit

I followed PR2 Opens a Door tutorial.

when I run

  hg clone https://kforge.ros.org/doors/hg
  svn co https://code.ros.org/svn/wg-ros-pkg/stacks/motion_planning_common/trunk/mapping_msgs
  svn co https://code.ros.org/svn/wg-ros-pkg/stacks/motion_planning_common/trunk/geometric_shapes_msgs

  export ROBOT=sim
  roslaunch pr2_doors_gazebo_demo pr2_doors_demo.launch
  rosrun pr2_doors_executive trigger_opendoor.py

It says:

  ira@ira-K42JP:~/code/ros/test$ rosrun pr2_doors_executive trigger_opendoor.py
  Traceback (most recent call last):
