The error is not about KF5DocTools. All the listed dependencies are defined by the ebuild, are they properly installed on your system? $ equery k kactivities kdeclarative kio
Yes, kactivities was not completely installed (but some files were!). I have /var mounted on an external drive, perhaps it's malfunctioning? Might that have led to the issue of an incomplete install? I have a new tool now for self help! Thanks as always.
Yes, you should check your hardware, urgently.
