One thing ROS is excellent is minimizing pain regarding installation.

In your case, assuming you've downloaded source code of the package you want to use along with some more packages you think you need, you may be 1) missing more dependency and/or 2) have incorrectly built your some packages.

Assuming you're on Ubuntu and ROS Indigo, for 1), go to the top directory of your catkin workspace where the packages above are downloaded. E.g. in a lot of tutorials, it is ~/catkin_ws. So cd ~/catkin_ws. If you don't know what catkin workspace, please go back to the basic ROS tutorial. Then run:

rosdep install --from-paths src --ignore-src -r -y

This command magically installs all the packages that packages in catkin workspace depend upon but are missing in your computer.

You seem to be troubled by rgbd_launch you downloaded source code of. But with the steps above, its binary should be installed so that you wouldn't have to download source and build by yourself.
