Isn't what you are thinking of here "the problem that several packages
have not been prepared for parallel build using 'make -jX' with X>1"?

If that's the case, then it's not so much a case of a bug in make, but
rather a problem with insufficiently specified dependencies in the
packages' Makefiles.  Since we're talking about third-party software
typically not exposed to parallel builds, I'd say it would be
difficult at best to fix all of pkgsrc's package Makefiles to play
nice with "make -jX", so following that avenue of attack to making
good use for more than one CPU is going to be an uphill battle at

Going into whishlist mode: Making use of multiple CPUs on a single
physical machine could be the relatively simple first step in making
it possible to spread package builds across multiple machines in order
to speed up package builds for a given architecture...  Clustered bulk
builds, anyone?
