[ros-users] tf Tutorials

Dear all,

In the tf tutorials, particularly in
http://www.ros.org/wiki/tf/Tutorials/Introduction to tf
I could not compile or get the dependencies by

$ rosdep install turtle_tf rviz
$ rosmake turtle_tf rvizIt seems like turtle_tf is no longer available.
My installation is ros-cturtle debian installed in /opt/ros/cturtle

How do I fix this?

Thanks in advance
Peshala
