Installing and running rviz

Following the instructions of the tutorial:

http://www.ros.org/wiki/rviz/UserGuide

1.-Installing rviz:

$ rosdep install rviz

When I tried to install rviz I got the next answer:

oscar@oscar-MAC:~/ros/ros$ rosdep install rviz
executing this script:
set -o errexit
#No Packages to install

As I couldn't install it I decided to look if I allready had it, so I tried to run it:

oscar@oscar-MAC:~/ros/ros$ rosrun rviz rviz
[rosrun] Couldn't find executable named rviz below /home/oscar/ros/stacks/visualization/rviz
[rosrun] Found the following, but they're either not files,
[rosrun] or not executable:
[rosrun] /home/oscar/ros/stacks/visualization/rviz
[rosrun] /home/oscar/ros/stacks/visualization/rviz/src/rviz

When I've got that answer I looked up on that directory (/home/oscar/ros/stacks/visualization/rviz) and then I compiled it:

oscar@oscar-MAC:~/ros/stacks/visualization/rviz$ rosmake

It compiled without problems but when I tried to run rviz it showed me the next message:

oscar@oscar-MAC:~/ros/stacks/visualization/rviz$ rosrun rviz rviz
[ERROR] 1280354462.238279000: [registerPublisher] Failed to contact master at [localhost:11311]. Retrying...

mmm it seems that I need to run roscore to fix the problem... well yes I runed roscore and in a new terminal I runed rviz and worked normaly XD.
