Now this looks interesting. Portpkg is basically a collection of SlackBuilds, and a port manager similar to Gentoo's Portage, and FreeBSD's Ports system, for Slackware. I'm reluctant to try installing it, since I've compiled and installed alot of stuff already with the standard tools, but I'd be curious to see how well it would run a freshly installed system.
