[ros-users] Something about PR2 Opens a Door

[Ken Conley]

Hi Bin,

The error is most likely because you have multiple versions of roslib
on your PYTHONPATH. Perhaps you are executing both the boxturtle and
cturtle setup scripts in your .bashrc. You can only have one. We will
try to improve the error message and setup in the future.

best,
Ken
