Were you in /usr/src when you tried to 'make buildkernel KERNCONF=blah'? 
  The buildkernel target is defined in /usr/src/Makefile.inc1 (included 
from /usr/src/Makefile).  Therefore, 'make buildkernel' will only work 
in /usr/src.  The handbook section on building a kernel the "new way" 
lists the steps as follows:
1) # cd /usr/src
2) # make buildkernel KERNCONF=MYKERNEL
3) # make installkernel KERNCONF=MYKERNEL

The handbook is a bit confusing on this.  It calls the config(8) kernel 
build the "traditional way" and 'make buildkernel' the "new way".  If I 
am a new user and don't want to stray far from the norm, wouldn't I pick 
the "traditional way"?  Shouldn't we make it more clear the "new way" is 
the "recommended and officially sanctioned way"?
