"Users are recommended to run the following command (pretend-only) to identify

in @world which have been removed, to help reduce conflicts:
emerge -pev @world -backtrack=0
Then for any "no ebuild available" messages, either resolve it by making
the needed changes, or emerge --deselect them. Then proceed to the world
