Hi Currently there are still some outstanding issues before we can really start using multiarch. You can find the status at the wiki page [1]. It seems that the main blocker at the moment is bug #618288 in apt. Please help to fix the outstanding bugs for the build tools (pmake, freebsd-buildutils, cmake) and apt so we can start using multiarch! Cheers Luk [1] http://wiki.debian.org/Multiarch/Bootstrapping
