I noticed a few things: 1) add a code block for emerge dhcp 2) dhcpd.conf needs to have ddns-update-style none; 3) /etc/conf.d/dhcp make sure you select the proper interface? I'll add more as I plug through this thing again.. I'll eventually get to patching this too, this bug is just so that I don't forget.
Fixed in CVS. Thanks for the feedback!
