Yes, I installed 2.1a15 ... I do a selfupdate everytime before doing

Ah ... I see these too ... but I wouldn't have known to go searching here.
man arpwatch doesn't bring up the manual.
Also running arpwatch it doesn't find ethercodes.dat for itself. I
had to move (and later update) ethercodes.dat in the /opt/local/sbin
directory alongside arpwatch itself. And there is no arp.dat file
created by the installer process. Nor is there the massagevendors
script for future updating of a current oui.txt from ieee.

Isn't it MacPorts policy to build necessary linked software itself
rather than rely on Apple installations?
