i posting this into bugzilla because it is listed in the rpm info and built
by redhat.

i tried to install kde 2.1 on redhat 7.0 and it has this missing
dependencies. "arts" seems to  the main one. arts is not even available for
7.0 as rpm.

kde 2.1 for redhat 6.x or wolverin seems to be ok.

error: failed dependencies:
