On my system, the program pkg_version can double its speed simply by
replacing "make -V PKGNAME" by "make BEFOREPORTMK=yes -V PKGNAME"
This is very cool! I've already added it to my devel version of portmaster in
several places. I call make a LOT in portmaster, so I went through every
invocation and added this wherever it worked (i.e., didn't cause a difference
in (or absence of) output.
However just because it works in a majority of cases doesn't mean that it
will work all the time. You just don't know what important thing might be
in AFTERPORTMK, which 99% of the time you never need.
So I see two approaches:
1. Add more .if's to bsd.port.mk so that there is a more efficient "make
VARIABLEONLY=yes -V variable-name" that does all the variables, but
doesn't calculate any of the targets - this might make things a bit
faster, or it might not;
2. Profile bsd make and see if there are any bottlenecks. I bet make was
never designed for speed in these kinds of situations. But this would be
a long term project, albeit definitely worth doing.
