Comment (by chrisjogorman):

 Yes `avr-libc` is installed.  I panicked when I couldn't compile some old
 source with the new `avr-gcc` and blamed the compiler not the old code.  I
 should have run
 `find /opt/local -name crtatmega162.o` or `port provides` as you have
 done.  The problem was with my Makefile and the old build steps.  Reading
 `/opt/local/lib/gcc/avr/7.2.0/device-specs/specs-atmega162` gave me enough
 tips to get the code built.  Now to change over a few `Makefiles`...
