Have a look at src2pkg
With that you can install almost anything
All the distros have a disavantage - one is sort of locked into what is available in their repository. Slackbuilds
is very good, but with src2pkg you can install anything that you can get to compile, as a package with two commands:
It's been around for some time - but I've just re-discovered it - because I needed it!
I really think that it could put to end the arguments that other distros have "better" package systems. Being able to install any
program that can compile in an orderly way without having to wait for it to appear in a repository, or to go through the steps of building a slackbuild script, puts slackware back at the front of all the other distros, as far as I'm concerned.
