Thanks again Mehmet, you pointed me in the right direction and with help 
from Dirk E off-list and Eduardo Morras here, I finally found the clue I 
needed, namely what USE_FPC in these Makefiles was about.  From notes:

For USE_FPC see:
/usr/ports/Mk/bsd.port.mk
/usr/ports/Mk/bsd.fpc.mk

smithi at x200:/usr/ports % find . -name Makefile -exec grep -l USE_FPC {} + \
	| egrep -v 'fpc-|lazarus'
./comms/cqrlog/Makefile
./games/hedgewars/Makefile
./lang/nbc/Makefile
./net-p2p/transmission-remote-gui/Makefile
./russian/emkatic/Makefile
./science/checkmol/Makefile
./science/mol2ps/Makefile
./x11-fm/doublecmd/Makefile

Eduardo pointed out hedgewars, Dirk transmission-remote-gui, but from 
that list I started with science/checkmol and mol2ps which are just the 
sort of thing I was after; single standalone programs built with fpc.

Even this monkey, having seen this Makefile, can do something similar :)
