Sorry for not explaining the assorted guts of the build system -
MAKE_PROGRAM is what gets called by bsd.pkg.mk to build one single
package. It is *not* intended to build more than one package at a time, as
there's probably little win in that (at least compared to the can of worms
you open to get things locked etc.). The changes I suggested affect both
only the "inner" part of the package compile.
Recommended reading: bsd.pkg.mk.
