buildworld fails with sendmail

BARTON# cd /usr/src/etc && make -DNOPROFILE

make: don't know how to make freebsd.cf. Stop
*** Error code 2

Stop in /usr/src/etc.

I searched the archives and found where  make -n freebsd.cf or make  
obj, make all would fix it.  No good here.  I also deleted usr/src/etc  
and did it again.  Any suggestions?
