Khmm, the only problems I'm aware off are poorly-written Makefiles -- and=20
jasper's was Ok. Are you alluding to a bug in a scheduler?
Actually, a better change is to amend the ALL_TARGET instead of MAKE_ARGS:
ALL_TARGET=3D -j`${SYSCTL} -n hw.ncpu`
This allows the port to _build_ faster, but still _install_ serially.=20
Install-targets create directories and that does not parallelize well in ma=
ny=20
autotools-created Makefiles.
Maybe, that was Marcus' problem?
