[ros-users] rosdep cannot resolve bluez

Fri May 7 18:44:20 UTC 2010

Hi Felix,
first off did you install stable, trunk or latest?
Furthermore, gdb will not work for pyhton nodes, sorry I did not
realize before it was about python. You would need to use pdb instead.
Can you run roswtf  and post please?

cheers, D.
