Well, actually, it's a granularity issue in the src/sbin/Makefile and its 
conditional handling of devd based on NO_CXX without taking into account 
whether we're building or installing.  Hence my comments about needing to 
provide some make infrastructure, since devd isn't the only component that 
falls into precisely this pit:

   SUBDIR= adjkerntz \
           ...
           ${_devd} \
           ...

   .if !defined(NO_CXX)
   _devd=          devd
   .endif
