Hello.
1. Your distro plz?
2. Umm, you do not install progs in Linux like in Windoze
3. Programs put themselves where they see fit
So, if you install a program from a tar.bz2 file or a tar.gz one:
1. Untar (or as windozers say : unzip )
2. login as root
3. open terminal (if you use KDE that would be konsole)
4. CD to the cat you have the untarred file
5. type "./configure" (without the colons)
6.after that is done, type "make" (without the colons)
7. then type "make install" (without colons)
Peace
