rosserial_python fuerte [closed]

In ROS electric I started connecting an arexx robot arm. I used rosserial_arduino as a starting point. And used a slightly modified rosserial_python on the computer side. Now I upgraded to ROS fuerte, and keep getting errormessages:

I'm fairly new to ROS and python.

My code is at :

Do I have to look up the changes in and incorporate them into my code. Or is it simply a matter of adding some directory to some search path?

I haven't used fuerte, but looks like python can't find rosserial_python, or ROS can't find the package.

What does this give? $ rospack find rosserial_python

Also, check your PYTHONPATH and that you are sourcing the correct stuff in your .bashrc.
