Don't sell yourself short ��

I'm sticking with pkgtools, so I have a prebuilt package from my own collection, I explodepkg in a ramdisk, then makepkg with usual options from SlackBuilds, only changing the extension of the package.
So I'm testing as much as possible what people would experience when slackbuilding, for the package creation itself only.

I did find out Slackware ships lbzip2, and pkgtools uses it if available, which is also a parallel bzip2, which renders it extremely fast on my 8-cores computer. I don't know the differences with pbzip2, or even bzip3, whose existence I'm discovering right now!
