Странная работа autounmask

Calculate Русский

Попытался размаскировать пакет app-office/karbon-2.3.3 и заметил что autounmask сгенерировал файл /etc/portage/package.use/autounmask-karbon со странным содержанием:

 # ---
 # BEGIN: app-office/karbon-2.3.3

Почему так произошло?

видимо это его зависимости

The following keyword changes are necessary to proceed:
#required by app-office/koffice-libs-2.3.3, required by app-office/karbon-2.3.3, required by =app-office/karbon-2.3.3 (argument)
=app-office/koffice-data-2.3.3 ~amd64
#required by app-office/karbon-2.3.3, required by =app-office/karbon-2.3.3 (argument)
=app-office/koffice-libs-2.3.3 ~amd64
#required by =app-office/karbon-2.3.3 (argument)
=app-office/karbon-2.3.3 ~amd64

Осталось то что после “The following keyword changes are necessary to proceed:” поместить в /etc/portage/package.keywords/karbon.

Я просто удалил /etc/portage/package.use/autounmask-karbon и karbon установился без проблем. Мне интересно почему один пакет с debug и -debug.
