Thanks for all the helpful notes.  It looks like I got my kernel
sources from the wrong place for what I want to do and that is the
root of my problem.

Once I confirm that I can build kernels again, I would like to
transition my system to -current.  What is the best way to go about
this?  What mailing list(s) should I be on?  What else should I
know about running -current?
