[ros-users] short dumps while executing ROS commands

[Ken Conley]

Hi Prasad,

roswtf is complaining because your PATH variables have both boxturtle
and cturtle on them.

>From the various commands you've typed, it appears that your
PYTHONPATH is set to prefer cturtle and your PATH is set to prefer
boxturtle. There are perhaps more issues, but that's all I can tell
without a dump of your actual environment.

If you've installed cturtle, it's probably best to switch to it 100%
so as to not have these configuration issues.
