Olá amigos, após rodar o comando emerge -avDNa @world tem retornado a mensagem de erro abaixo.Quando eu retiro do comando a opção D rodando o seguinte comando emerge -avNa @world funciona normalmente.Me parece que o erro acontece ao tentar atualizar as dependências,mas não sei como proceder para resolver o problema, por isso necessito da ajuda dos amigos.

Calculating dependencies... done!
