In revision 1.223 of kdelibs.spec Rex commented line: {?_with_libutempter:Requires: libutempter-devel} This change break compilation of Krusader in rawhide (you can see logs in task 85666): /usr/bin/ld: cannot find -lutempter collect2: ld returned 1 exit status make[3]: *** [krusader] Error 1
See also bug #253801. It's not kdelibs at fault here. I'll go take a closer look in krusader.
In the meantime, a quick-n-dirty added: BuildRequires: libutempter-devel can help here.
Yep, it's kdebindings(-devel) that's to blame, and needs a rebuild.
In particular, libkjsembed.la containing -lutempter will get purged on next respin.
Should be fixed now with kdebindings-3.5.7-5.fc8
