Несколько дней назад поставил себе Гном 2.28.1 из оверлея, а сегодня при обновлении выдает следующее:

rmcfs ~ # emerge -avuDN world

Подскажите пожалуйста почему уменьшается версия Гнома?
PS При попытке установить Гном на другом компьютере ставится версия 2.26.3 и из оверлея и из оффициального дерева.
