Use gmake instead of make, as you're supposed to do on BSD. From INSTALL:
[ ... etc. ... ]
Yeah, I always normally use gmake ... but this time, due to an unrelated
error, my local PATH got set incorrectly when I logged into the "courier"
account on my system. This caused a script that usually comes first in
that PATH to be incorrectly ignored:
script file: ~/bin/make
exec /usr/local/bin/gmake "$@"
Fixing the unrelated problem so that my local PATH is set correctly
(thereby causing this script to once again be invoked whenever 'make' is
requested when I'm logged in as "courier") solved the problem.
