(I cannot specify arpwatch as package in bugzilla, and since
its in the same source rpm as tcpdump, I filed it here)

arpwatch advertises in its description that it comes with
arpsnmp. The source in the SRPM comes with arpsnmp. In the
arpwatch binary RPM arpsnmp is missing. Also, the scripts
to use arpsnmp (arpfetch, bihourly) are not in the RPM.

The easier fix might be just remove the arpsnmp announcement
from the package description, since its only rarely used
(though I happen to have usage for it)
