Khmm, the only problems I'm aware off are poorly-written Makefiles -- and 
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= -j`${SYSCTL} -n hw.ncpu`

This allows the port to _build_ faster, but still _install_ serially. 
Install-targets create directories and that does not parallelize well in many 
autotools-created Makefiles.

Maybe, that was Marcus' problem?
