Any packages that are not reachable from @world are ripe for removal by
--depclean, so we allow their dependencies to break in order to satisfy
other dependencies (like in bug 563482). If you don't use --deep, then
emerge may try to build something that depends on one of these
unreachable packages with broken dependencies, such that whatever you
are trying to build has broken indirect dependencies (which is likely to
trigger a build failure like in bug 563482).
