installing gazebo in a overlay

edit

hello, i trying to install a different version of gazebo like a overlay, i create my workspace and run the following lines:

rosws set --svn simulator_gazebo https://code.ros.org/svn/ros-pkg/stacks/simulator_gazebo/tags/simulator_gazebo-1.7.6

and the

rosws update

but i obtain this:

virtualtouch@ubuntu:~/fuerte_workspace$ rosws update 
[simulator_gazebo] Installing https://code.ros.org/svn/ros-pkg/stacks/simulator_gazebo/tags/simulator_gazebo-1.7.6 (version None) to /home/virtualtouch/fuerte_workspace/simulator_gazebo
