{gentoo} qemu внутренние неразрешимые зависимости. Помогите.

Хотел обновить мир, но у qemu возникли проблемы (раньше нормально собиралось).
Как только флаги не крутил, то же самое. Подскажите, что делать?

Выдало следующее:

# emerge --backtrack 70 --autounmask-write -av --newuse -u world
FEATURES variable contains unknown value(s): preserved-rebuild

* IMPORTANT: 6 news items need reading for repository 'gentoo'.
* Use eselect news to read news items.


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