Funny that this discussion should come up here at about the same time
as a very similar discussion on a Debian list :)

IMHO, hardcoding the number of jobs in the port's Makefile would not
be the best approach.  I think a port should only flag whether it
supports parallel building at all or not - and leave the number of jobs
to either the ports framework or the administrator's choice.

The ports framework may pick a value - ncpus, or ncpus+1, or ncpus*2, or
something like that - but, again IMHO, the administrator ought to be
able to override it in any case.

Other than that, it's great that y'all are actually doing something
about supporting parallel builds! :)

G'luck,
Peter

This sentence every third, but it still comprehensible.
