Hello, I'm a noob when it comes to ROS and am not one to resort to asking for help unless I've exhausted all other avenues. I've got ros indigo running on a Rpi with the latest wheezy and managed to get through the initial tutorials successfully, roscore, rosnode and so on. I'm now trying to work my way through the tutorials that get the arduino to behave as a node usine rosserialarduino. I've followed the *'rosserialarduino/Tutorials/Arduino IDE Setup'* totorials to completion and began working on the next tutorial - 'rosserial_arduino/Tutorials/Hello World'

I have one terminal running 'roscore' and open a new terminal to execute: rosrun rosserialpython serialnode.py _port:=/dev/ttyUSB0 after a few moments I get : [rospack] Error: package 'rosserial_python' not found

Any help would be very much appreciated. Thank you
