How do I install a Hokuyo node on a Raspberry PI running groovy?

edit

The system has Ros running on Rasbian (Groovy-Wheezy) on a Raspberry Pi. I can run TurtleSim and rqt-graph and see the nodes, etc. Is it possible to load the Hokuyo node drivers and run the node without using Rviz? It looks like it's possible to dynamically re-configure the Hokuyo to set clusters, etc.

If I could use rosmsg show (laser data) then I believe we could use the Hokuyo with the Raspberry PI to do some robot navigation.
