I was talking about dependancies inside the same packages. For example,
a package providing a library, and binaries using this library.
If there isn't an explicit dependancy on the library in the makefile,
and it rely only on rule order processing, a parallel make will probably fail
(will try to link programs before the library is done).
This is an issue in the package's Makefile themselves, not pkgsrc,
and fixing all thoses is a lot of work.

Sure. I'd like to be able to use a cluster of m68k to build packages too :)
