If I remember correctly, the package to which you refer is one of the extensive alternatives available to you from the KDE Desktop. Some people don't include all of the alternatives in an attempt to cure some of the "bloat" in a "full" installation of KDE.
Unlike much of the "Windows" interface, you can actively remove (or add)any component which you do not use in any of the applications in Linux. Unfortunately, this also means having to take the responsibility to learn about the dependancies of each component you choose to have. You have to come up with your own: getting exactly what you want -vs- how much of a pain-in-the-ass it is to learn how to accomplish it--ratio. I have a low pain-tolerance, but I have been known to dink with kernel sources to get what I want--if I get pissed enough. (Usually, the next patch available does exactly the same things, was released before I "dinked", and I had been too lazy to do a search to find out. I can be pretty dense sometimes.)
The only other comment I have is that most of the applications found on any version of linux including the kernel are available as "vanilla" packages.
These packages are normally the source-code for the application which has been compressed using tar and b-zip (or b-zip-2). This is known as a "tar-ball".
Generally, doing a search from http://www.google.com/linux
using the name of the package or application will give you an address for download.
You will want to do some reading on your specific distribution on any changes you may need to make in the "make-file" of the package when you expand it, and the suggested location to expand the package.
Also, most packages have documentation located within them--documentation written by the package maintainers available no where else:
Package documentation supersedes any other docs for the application.
Most often, there is a set of instructions on how to install and tweak your package for use with specific distributions and/or desktop configurations. This is the best means of getting the highest performance and the greatest stability for your Linux installation.
/* In the end, there really isn't such a thing as a "distribution". Why? Because you will customize Linux to your own specific needs and desires--you are only limited to the extent of the dependancies the packages you choose. You will, in essence, "roll-your-own" distribution.
The only situation in which you will not do any customization is if it is a server set-up for a business which has: No policies in place for appropriate equipment-specific log-books; no training; no trained staff; and no budget. (That situation applies to "Windows" installations as well.) Then, the emphasis is upon back-ups, maintenance, and hopefully--security. (Which really involves at least some custom work regardless of the O.S.-- but try to explain that to a pointy-haired-boss.)*/
There is a tremendous amount of information on how to expand and install different applications from source out on the net (And here on this site if you do a search).
Never give up after one search or one explanation.
Linux-users all over the world are constantly writing guides and tutorials on how to do things. Each person approaches the task in a slightly different way--or explains the process in different words and terms.
Try to always find and read three of these guides or tutorials before you attempt something new. If you still don't "get" it; chances are you need to go back and learn something.
No matter what it is you may want to do in Linux, someone somewhere has written down instructions of how it is done, the hardest part is learning how to search.
