Currently all kde4 ports marked as jobs_unsafe, because of automoc4 hangs.
The problem can be easely reproduced building e.g. accessibility/kdeaccessibility4
with multiple jobs: replace MAKE_JOBS_UNSAFE with MAKE_JOBS_SAFE in port Makefile
and run 'make MAKE_JOBS_NUMBER=16'. Build will be freezed on
