How do I install Stage and stage_ros?

edit

I'm a bit new on ROS and I'm having some difficulties installing Stage on my computer. I'm trying to install this package http://wiki.ros.org/stage and http://wiki.ros.org/stage_ros . I git cloned stage_ros into my catkin_ws and when I tried to catkin_make it I was missing Stage. The problem that I'm having is to know where and how to install Stage. After that I'd like to implement joystick control but I want to get this sorted out first.

Thank you.

This is the error that I get when I try to catkin_make:

I'm using Xubuntu 14.04 which I think would work for the apt-get install but I just need to know that right commands. What I've been doing is following this tutorial to install Player/Stage http://rtv.github.io/Stage/install.html and this one as well http://ranger.uta.edu/~gianluca/astra...
