[ros-users] cturtle: cannot find executable named rviz

Hi,

I encountered a problem while running rviz in cturtle. I'm thinking it might
have to do with the instability in vision packages in cturtle... The error
message is posted below. If it indeed is a problem related to cturtle's
vision package, please let me know the commands for updating the rosdep.yaml
and other solutions for fixing the linking problem.

yglee@yglee-laptop:~/cturtle/ros/humanoid/stacks/interaction-ros-pkg/sandbox/person_urdf/build$
rosrun rviz rviz
[rosrun] Couldn't find executable named rviz below
/home/yglee/cturtle/stacks/visualization/rviz
[rosrun] Found the following, but they're either not files,
[rosrun] or not executable:
[rosrun] /home/yglee/cturtle/stacks/visualization/rviz
[rosrun] /home/yglee/cturtle/stacks/visualization/rviz/src/rviz

Thank you in advance!
