I'd guess you did dmake -P2 in the top level directory ? The top level makefile.mk only really calls "build.pl", try this cd instsetoo_native/util build --all -- -P2 that'll call "dmake -P2" every time dmake would normally be called, additionally you can make build.pl attempt to build parallel modules at the same time, e.g. build --all -P2 or to go nuts, both together build --all -P2 -- -P2 Finally, export MAXPROCESS=2 is an alternative way to trigger dmakes to be -P2 so build --all -- -P2 and export MAXPROCESS=2 build --all are the same. parallel building is a sort of "your mileage may vary" kind of thing. Sometimes inter-module dependencies for build's -PX need fixing, and sometimes makefile.mk's for dmake's -PX need fixing, so I always build parallel, but with a check for failure and restart unparallel on trouble. That said, with OOC680_m2 I don't think there's any problems with parallel dmake makefile.mks, and only one module interdependency problem that I know of which your unlikely to hit.
