xpt_* missing symbols are due to CAM being removed from your kernel
configuration.  You'll need "device scbus" and "device da".

ieee80211_* missing symbols are due to you attempting to include some
wireless USB drivers; you'll need "device wlan".

A few things:

1) Your kernel configuration may be "out of date" compared to GENERIC.
GENERIC is updated often; sometimes device names change, or things are
removed/replaced or added for needed features.

I assume your CK config is outdated since the box was last built in
July.  I recommend doing cp GENERIC CK and then editing CK to your

2) Did you rm -fr /usr/obj/* before starting this build?  If not,
try it.  There may be old cruft in there from July.
