Please check whether you installed aRts correctly. Sure it is not there, arts is not there! And arts should not be required! This is caused by too old autoconf-rules. Or from source tarball-view: Too old admin-directory. When replacing the admin-directory with one from a new kde-tarball and calling make -f admin/Makefile.common a new configure-script is created which can work also without arts. This problem is the same as with kvdr, bug #112177. There updating admin/, recreating configure and repacking has helped.
No need for repacking, I leave an admindir package around for cases like this :) Fixed now, thanks for reporting!
