By the looks of it, you need to locate the packages that adds those files it needs and ever convert them or compile them yourself. I tried googling earlier and got to a rpm search site.

Conversion of the packages either failed (mandriva ones - stay away from i586 packages) or they throw up unknown dependancies (Freshmeat i386 package - would work, but you have to figure out the missing requirements).

Try search for these files in a trial and error kind of way. If it gives you a WARNING missing requirment for... then it works. If it gives you could not locate /depends, it probably won't work. You could probably also try straight deb files from the latest Ubuntu.

I wish you luck - converting packages can be a bitch, but this is an awesome game. Alternatively, I played it in wine a while back when I was still on Ubuntu - Maybe you could do the same ^.^

I downloaded libstdc++6...deb converted and installed it. I also removed libstdc++5 - same error...

By mistake I linked libstdc++.so.5 to libstdc++.so.2. I then only removed the link

rm /usr/lib/libstdc++.so.2

After that applications like notecase and firefox refused to start because they miss libstdc++.so.6 (or libstdc++-libc6?) and now I cannot start the Xserver (textconsole is working anyway).
Is it because the converted libstdc? I don't think that removing the link could have caused this?!

I tried it earlier too and it's dependencies are way weird. I think it's expecting a fedora system or something. I also know that debian based distro has a bad habit of post-fixing drivers with debian. I've had no end of trouble with it...

Any idea what to do about my current problem? Or should I start a new thread?

For starters:
Keep a backup of slitaz you can restore when you break it.
