[ros-users] Problem launching pr2_dashboard and friends

[Anand Atreya]

Thanks, Ken.  It looks like the PYTHONPATH was the culprit.  Boxturtle's
roslib was first since the .bashrc was still loading boxturtle's setup.bash.

Is there a standard procedure for using cturtle (or some other distro) on a
robot with boxturtle installed as the default?  The /etc/ros/cturtle
directory is missing, and I know that's the proper way to get all the
necessary environment variables set.  Should that have been created as part
of a cturtle debian package?

Thanks.
