There is bug report 714, kio_man does not work with some distros. The reported problem affects run-time and not compiling, but try applying the patch to tdebase and see what happens?

I rebuilt everything Saturday and experienced no such build error. I have been applying that patch for many months.

There was one commit several days ago (513ffc6e) that requires rebuilding tdelibs as well as tdebase, but I don't think that patch is related to your problem description.
