Fixing them is not enough, you must also put the required annotations so that various update scenarios will work.
Case in point: libffi. We noticed a while ago that it was conflicting with gcj, and so Jasper updated gcj so that it would no longer install libffi (since it's only using it for building)... he also promptly forgot to add a @conflict marker to libffi. And so, I found out some update scenarios would fail: gcj and py-gobject from 4.6. Update to snapshot would fail: in current, py-gobject depends on libffi, and libffi install *requires* updating gcj first... which pkg_add won't figure out without the proper @conflict marker.
