Hi, I installed pre-compiled version of boxturtle on ubuntu :http://www.ros.org/wiki/boxturtle/Installation/Ubuntu/Deb I also installed some of the nodes separately : teleop_base, control_toolbox,hokuyo_node. I want to make sure that there should not be any conflict between boxturtle and cturtle. Thats why I want to clean everything and then install cturtle. Barton
