Yesterday was the first day on this part of the project. Box score for the day isn't horrible:
kdelibs: Succeeded after 8 hours, 4 minutes, and 29 seconds.
kdemultimedia: Succeeded after 42 minutes, and 57 seconds.
kdegames: Succeeded after 2 hours, 56 minutes, and 16 seconds.
Unfortunately kdelibs needs rebuilding with Soprano. kdepimlibs requires Nepomuk support, so this has to be compiled into kdelibs.
Today, got the rest of kdesupport updated (kdebuild-src doesn't seem to handle the case of kdesupport elements that have moved to Git already, but that may just be my unfamiliarity with the tool). With that done, kdelibs is building again and kdepimlibs is next up. The dependency relationships between the different KDE SC modules is comples. It's charted (current for KDE 4.5) here: https://wiki.kubuntu.org/Kubuntu/Ninjas/DependencyGraph
