[ros-users] teleop_base

in this tutorial http://www.ros.org/wiki/simulator_stage/Tutorials/SimulatingOneRobot
we need to install teleop_base.

i've installed teleop_base and can navigate to teleop_base package by "roscd teleop_base"
but when i run "rosmake teleop_base" it gives the following error(only displaying the last few lines of the terminal)

rosmake ] [ 32 of 34 Completed ]

[rosmake-2] <<< control_toolbox <<< ROS_NOBUILD in package control_toolbox
