Sean,
The error it's complaining about suggests that the computer citadel.local
doesn't have ros installed in /home/sanderson/ros If you don't have NFS or
an other shared file system you need to make sure you have the same paths,
or you need to set ROS_ROOT and ROS_PACKAGE_PATH for the machine tag such
that roslaunch can find the ros stack and other stacks on the remote
machine. See
http://www.ros.org/wiki/roslaunch/XML/machine
In particular, I note that your username on citadel.local is mpurvis but
your path exports /home/sanderson/...
