I am completely sick about this, every time i try to install a program from source it has lots of dependencies, and that dependencies has new dependencies, and forever and ever until suddenly one of the dependencies DON'T work for some reason. Is there a program or a magical trick that could help me a little bit with that?????

Slackware is not for newbies. I have been using Linux for two years, putting at least 16 hours a week into learning, and I don't like to install Slackware. It has a cool name, but is rather behind the times. I'm gonna get some grief for that last statement, but it is true. Try Ubuntu 6 (Dapper Drake) and not the live install, but the alternate. Fedora Core 6 is also a great desktop distro and easy to install.

NO

First, if you are getting sick trying to make your computer work, it's time for a new pasttime......

I now have a machine running with ~8 distros installed (I've lost count.... ) The stable workhorse distro de jour is Mepis. When I want to play, I simply re-boot and go try to make one of the others work. Mepis is the default so--when my wife wants her turn-- a simple "reboot" gets her to the stable system and her e-mail + shoe-shopping.

I would now pick distros largely by the quality of their package manager. With Debian/Ubuntu/Mepis, synaptic and adept are both good. Arch is wonderful.
Another good one is PCLinux OS--Mandrive-based, but with synaptic package manager.

I personally see no reason to suffer with things like Slackware and Gentoo. YMMV.

Guiding by your level of frustration, i think u have chosen the wrong distribution.

Debian, Kanotix, Knoppix, Ubuntu all come with the Advanced Package Tool which generally makes things much easier. apt looks up a list of sources (e.g Debian repositories ) and is able to download all the dependent packages if they are in the repository.

Altho apt is a command-line tool, there are GUI frontends like KPackage available.

I started using Debian and Kanotix and still find it very difficult to use something other than Debian-based.
