Let me pick a simple one without specialties: rxparamedit.
Given you installed from packages in Ubuntu, the first step would be to check if there already is a debian package that you can just install. Usually that is named ros-<distro>-<stack/metapackage>
. The nav-bar in the wiki shows the stack a package is in, which in this case would be freiburg_tools. For fuerte you'll find that sudo apt-get install ros-fuerte-freiburg-tools
works.
If there is no deb package, you have to install by sources. rosws/ws_tool is recommended for that. The wiki page should list a source URL, e.g. https://alufr-ros-pkg.googlecode.com/svn/trunk/freiburg_tools. The rosws tutorials show how to do this in more detail, but basically rosws set --svn https://alufr-ros-pkg.googlecode.com/svn/trunk/freiburg_tools
and rosws update
should do the trick.
Next, build the package by rosdep install rxparamedit
and rosmake rxparamedit
or catkin_make
if the package is catkinized .
Are you interested in that one specifically or ROS packages in general. The example you picked is somewhat more complex. It seems to be for web apps (not "only" ROS) and it looks to me to not be maintained anymore.
