I will write about it more in detail on vivaPowerPC, but I decided to put things I slackbuild for my machine on the server for others. I try to mimick well known structure of Alien's SlackBuilds as much as possible.
There are only few packages there, well I just started, SlackBuild scripts have the ppc64le section added and if possible I try to build from as fresh versions as possible. The source package used to build is also in the build folder.
I'm adding single line with my contact to every SlackBuild script, so people can send curses directly to me and not to the original maintainer.
If anyone of you is brave enough:
