HI Eileen,
What sort of hardware do you have? I suspect it might be a problem with not having sufficient graphics support. What does 'glxinfo' say?
I've just updated the tutorial to run headless without the need of a compatible GLX driver, can you give the new instructions a try?

Thank you.

Dear ros-users:
I am learning Building a Map in Simulation in the website of http://www.ros.org/wiki/pr2_simulator/Tutorials/BuildingAMapInSimulation. When I begin to run the second step "roslaunch pr2_gazebo_wg map_building_demo.launch", it gets errors showing in the accessory. And the error happened in the last three lines in the error.txt. What happened? Thanks in advanced!
