i've been doing a little bit of work in the source tree to enable
users to override the owner/group of ``normal'' files (i.e., non
set-id, etc) from bin:bin to something else (in my case, root:wheel)

to enable this, put something like the following in /etc/mk.conf:
	BINOWN?=root
	BINGRP?=wheel
	DOCOWN?=root
	DOCGRP?=wheel
	KMODOWN?=root
	KMODGRP?=wheel
	LIBOWN?=root
	LIBGRP?=wheel
	MANOWN?=root
	MANGRP?=wheel
	NLSOWN?=root
	NLSGRP?=wheel

and rerun 'make install'.
