as now, you can handle that with an eclass that takes deps, checks those
deps with certain use if the use has been enabled and dies if those
criterions aren't meet (asking you to falling back to hc-updater to keep
those applications in shape)
pretty hacky and itchy but that's probably the best you can do w/out
use-deps. (PS can you slot on use now?)
