This snippet needs to be associated with some sort of make target or it
will never get run. You can do something like this:
DIRS=3D /var/lib/${PORTNAME}/movies \
/var/lib/${PORTNAME}/plugins \
/var/log/${PORTNAME} \
${ETCDIR} ${ERLYDIR} ${WWWDIR}
=2Efor dir in $DIRS
dirs :: ${dir}
${MKDIR} ${.TARGET}
=2Eendfor
Or you could have just one target and put a shell loop as the action:
DIRS=3D ...
dirs :
for d in ${DIRS} ; do \
${MKDIR} $$d ; \
done
Note the backslashes so that make(1) executes all of that as one
command, and the required use of ';' to mark the end of the different
shell statements.

No -- that's not the case here. You need to do this if you have a shell
for-loop as part of the action of a target (the second example above),
as $$ causes make to pass a literal $ through to the underlying shell,
rather than expanding it as a make(1) variable.
Cheers,
Matthew
