sudo apt-get install python-scipy python-opencv  python-pip python-pexpect python-tk
sudo pip install --upgrade pymavlink mavproxy

ardupilot install script is handling this. Probably need to update the wiki to update the packages

Thanks. Do you think we should say for Linux to just run the installer?

we should probably add an install script for mavproxy, that would be easier to maintain. On side not, you don't need to install wx, opencv, and matplotlib if you don't need GUI stuffs
