[SOLVED] autounmask требует нестабильный пакет

emerge -uNDa world получаю

!!! All ebuilds that could satisfy "~dev-lang/perl-5.10.1" have been masked.
!!! One of the following masked packages is required to complete your request:
- dev-lang/perl-5.10.1 (masked by: ~x86 keyword)

(dependency required by "virtual/perl-Scalar-List-Utils-1.21" [installed])
(dependency required by "dev-perl/IO-Socket-SSL-1.33" [installed])
(dependency required by "dev-perl/PortageXS-0.02.09" [installed])
(dependency required by "app-portage/autounmask-0.27" [installed])
(dependency required by "world" [argument])

Снес app-portage/autounmask , проблема решилась. Только вот как ее понимать я совсем не въехал.
Все пакеты из dependency required стабильны.

В ebuild autounmask тоже как бы не к чему придраться
