Judging from your other questions, I'm guessing you've only just started using ROS. Have you completed (and understood) all the ROS tutorials on the wiki? If not, I'd highly recommend you do those, as they will help you understand what is going on.

Type echo $PYTHONPATH To get an idea of what paths are linked.

Also don't do what I did and waste a day running a script from the folder it is in, i.e : ./script.py, run from the previous folder, i.e ./scripts/script.py
