How do I install ros-hydro-ros-comm on Arm?

edit

When trying to install ros-hydro-ros-comm I get:

The following packages have unmet dependencies:
 ros-hydro-ros-comm : Depends: ros-hydro-roslisp but it is not going to be installed

I am using the Arm instruction on the Wiki with sources at:

deb <a href="http://packages.ros.org/ahendrix-mirror/ubuntu">http://packages.ros.org/ahendrix-mirror/ubuntu</a> raring main

So how do I resolve this? I noticed that rostopic did not exist and that I was missing this packages.
