After doing that again cat the pid file and compare it to the PID for dhcpd.
If it looks right you can try copying to /var/run/dhcp/ and run rc-status 
again, if it works this time then portage is looking for the pid file outside 
the chroot. You set it up using the DHCPD_CHROOT in /etc/conf.d/dhcpd right?
I don't use that option since I use apparmor but it looks like the init script 
will do the right thing in traccking the pid file if setup correctly. Are you 
using the latest version (may need to run etc-update)?
