Ah! I got these errors too some time ago. Apparently, I had been a little 
careless while cvsup:ing at that time.
I'm on a 4.8-STABLE system, and I accidentally cvsup:ed with the wrong 
cvsup file, ending up with -CURRENT
code all over the place. No good! So, if you've accidentally fetched some 
-CURRENT code to your -STABLE
system, that might be it. Try cvsup to your current system and try again...

Doesn't it? I think it does, I tried it some time ago, but i've been wrong 
before! =o)

Good choice... in the long run. But keep in mind that FreeBSD is made for 
Tinkering(TM).
You could (should) always back up a functional kernel before installing new 
ones. That way,
you don't have to worry about screwing up. You could always go back and 
undo/redo.

Don't know if any of this helps, but anyways...
