Глюк emerge: постоянный rebuild для половины пакетов

С недавнего времени (но не могу точно сказать после чего именно) наблюдается следующая проблема: есть целый список пакетов, которые emerge хочет перестроить [ebuild R].

Первый раз я обратил внимание на большой список для перестроения, когда после очередного emerge --sync; emergee -Dpv world нужно было обновить openssl. Я подумал, что это нормально, т.к. от openssl действительномногое зависит. Но длиннющие списки на rebuild стали появлятся и при последующих обновлениях. Я почуял что-то неладное.

Затем я вручную выполнил emerge --deep для всех новых пакетов [NSU], таким образом остался список пакетов только с [R]:

# emerge --deep --pretend world

These are the packages that would be merged, in order:

Хорошо, я перестроил их: emerge --deep world, всё завершилось без ошибок.
Но после этого emerge -Dp world выдал точно тот же список!!

Я выполнил revdep-rebuild, но несоответствий не было найдено. Я выполнил emerge --regen и emerge --metadata, но ничего не изменилось! В итоге, я просто понятия не имею, как побороть это баг.
Вот информация о моей системе:
