zrj and I got kd5-webengine working, so those ports will ultimately make it into the repo. However, zrj says there's a big version update coming to all the kd5 stuff so he's decided to integrate the webengine fixes into that work. DragonFlyBSD will thus definitely see a working kd5-webengine and most of the dependencies, but it may be a month or two.
