kdelibs-2.0-7.i386.rpm from ftp.kde.org does not include the KDE documentation (/usr/share/doc/HTML/*)
Oops, the fixed kdoc wasn't installed on the build server. The spec file is ok, so simply recompiling this on a system with a working kdoc fixes the problem. The Red Hat Linux 7 version fixes the problem, too.
I've recompiled the package, the docs are still not included. I suggest adding %dir %{prefix}/share/doc %{prefix}/share/doc/* to the %files section of the main package to include the doc files under /usr/share/doc/HTML/*
Oh, the main package. It's not supposed to contain the docs. Since the docs in kdelibs are about the API (programming the libraries), the right place for the docs is in kdelibs-devel, and they're there.
