Configure a package

[Zantgo]

Some of you busy FreeBSD or Gentoo, the grace of these systems are personal settings that everyone can get in the installation of each package, for example because in gentoo by the USE variable, everyone can put there by example "gtk -qt ", which eans that for each installed package support for gtk (Gonome), and remove support for qt (kde), because in this case the user is occupying Gnome, then you need support for KDE. The same would be if I install the same package on FreeBSD, but this is set during installation of the package, in this case, while a menu will be installed based on X Window, which let you choose what you want to install and what not, this case the user deactivate and activate gtk qt. In these two systems packages install things through the source, a significant difference in relation to RedHat. These are my questions:

- Can you get this kind of advanced configuration of RedHat packages, either by source or RPM?
- Redhat has advanced management tools with the sources?
- In the event that this can be Where I can get this information how?

Thanks in advance Zantgo
