From Bugzilla Helper: User-Agent: Mozilla/4.75 [en] (X11; U; AIX 4.3) RedHat 6.2 had kdat as a part of kdeadmin. The www.kde.org indicates that kdat should be a part of kdeadmin. - Its missing Reproducible: Always Steps to Reproduce: 1.File is missing 2. 3. Actual Results: command not found Expected Results: execution of program For people that used kdat for backups this could be a large problem....
I've looked at the code; it seems to be excluded intentionally (configure.in.in from kdeadmin clearly states DO_NOT_COMPILE="$DO_NOT_COMPILE kdat" unconditionally). I'll talk about this with the kdat maintainer.
kdat was removed intentionally because it doesn't work.
