Hello, I have a celeron 600 with 320 mb ram. I used to run slackware
linux from many years, but I would like to know if there is another
distro that can run so good on my older pc, but contains a great
amount of packages so I can install an app that requires many dependencies and not become insane.
Thanks,
tano

You can try ArchLinux http://www.archlinux.org/ It's lightweight, and has a nice package manager, pacman.

I recently installed Debian Etch on a system that is roughly half of the power that you mentioned, and found that it is relatively fast enough for all intensive purposes. Debian also has a vast amount of packages available to it as well, and using apt-get is relatively easy to do. With Synaptic, dependencies are also resolved for the most part, similar to YaST in the SuSE distributions.

Just out of curiosity, what has changed your mind to switching from Slackware? If you're like me, I like to try other distributions to compare the differences between them, hence the reason I have multiple computers. I've tried the virtual machine route, but it just did not seem to offer the same experience.

If you want to go the Ubuntu route, you can find info here:

AntiX will give you Mepis, with access to all of the Debian testing repos.
Fluxbuntu should run fine.
PCFluxboxOS will give you access to PCLinuxOS.
If you install Mandriva off the DVD you can choose a lighter desktop environment.
Coming from a Slackware background, you will probably be comfortable with Frugalware. That has a very good package selection and uses Pacman taken from Arch.
Of course, my current favorite is Arch, so I will recommend that, if you can handle the absence of stable releases.

I would like to try some software like Ardour (Ok, the pc is older also
for ardour, but only try) or other that requires so many libs that is
very frustrating to compile, the best solution for me (not technical, I know) could be to find some site that gives "huge statically linked
software for free" ;-)..

Well, I don't mean to sound like a used car salesman, but ArchLinux has ardour in their repositories
http://www.archlinux.org/packages/search/?q=Ardour+
which means the installation will be as simple as

pacman -S ardour

for you.

Vector Linux, http://www.vectorlinux.com, is build on Slackware and proclaims to be ideal for older systems.

I think any distro with the possible exception of Suse/OpenSuse will run fine on those specs.
