In fact, that is the usual way.  Well, most ports probably don't
bother with Makefile dependencies and just run the substitution
from a configure/build/install rule.

Try

$ find /usr/ports -name Makefile | xargs grep pkg-install\\. /dev/null

Among plenty of chaff, this turns up a number of ports that generate
pkg-install from pkg-install.in etc.
