Как исключить пакет из списка зависимостей? [ SOLVED ]

#emerge --inject linux-headers -p glibc
*** --inject has been deprecated.
*** If you manage a piece of software yourself, add it's name and
*** version (eg foo/bar-1.0) to /etc/portage/profile/package.provided.
*** If you want to prevent portage from upgrading a package, add it to
*** /etc/portage/package.mask prepending it with '>' (eg >foo/bar-1.0)
*** For more information on fine-grained portage control, please see
*** the portage man page.

Создание файла /etc/portage/profile/package.provided с добавлением строки sys-kernel/linux-headers решило проблему.
