In addition to all of the other comments, there is one more point to
make clear; although parallel builds work fine, they obscure the
output from the different paths of the build.  Therefore, if you have
trouble with a "-j" buildworld, the first thing you need to do is to
run it again without the "-j".  This is not because it might work that
way, but because the error messages will be much easier to understand.
