Here is an ebuild of rarpd-1.1. I found when trying to use rarp that there was no rarpd installed or available in portage. So, I made an ebuild. net-misc/rarpd might make a nice home for this. This package depends on libnet and libpcap (which are allready in portage). any questions on this, just bug me on irc (I'm Alron there)
