Yeah, you saw this right. Patrick of Slackware fame put KDE 4.1 packages from Robby Workman and Heinz Wiesinger to the Testing branch. Thank you very much to both of you for doing the hard work. I knew that Robby has been working on KDE 4.1 packages since ~4.0.60 but that’s beside the point. I know how hard it is to track dependency requirements down. One day the packages needs Akonadi and the next day it requires boost, go figure. I tried to hunt and compile some of those packages but to tell you the truth, Robby and Heinz are much more experienced then me which doesn’t mean that I’ll stop trying. 
The packages dependency requirements aren’t really clear for the uninitiated. I had to figure out why X package wasn’t building like for example, it gave an error that say something along the line of akonadi library is not found. Ahhh, what is akonadi, never heard of that before. Google. Poof, there you go, it’s part of the PIM framework and not the movement for racial justice. So, for example now I started to follow the release team KDE mailing list as this makes sense, doesn’t it?
Back to KDE 4.1 Slackware packages now in Testing. Here is what Patrick had to say about this in the current changelog.
Thanks to Robby Workman and Heinz Wiesinger for all the packaging and testing help, and of course to the whole KDE community for helping to bring the Linux desktop to a whole new level of appearance and ease of use. I’ve installed this on my main email/browsing/general machine and as far as I’m concerned there’s just no looking back. It’s really a big step forward.
Again, thank you Robby and Heinz.
