Gentoo无法安装Grub2

[nehc]

安装Gentoo handbook 安装，在最后安装Grub时，我选择安装Grub2：
按照Gentoo wiki的方法：http://en.gentoo-wiki.com/wiki/Grub2

# echo "sys-boot/grub:2" >> /etc/portage/package.accept_keywords
# echo "sys-boot/grub:2" >> /etc/portage/package.unmask
# emerge -av sys-boot/grub:2

出现 如下错误：
#emerge -av sys-boot/grub:2

Total: 22 packages (22 new), Size of downlaods: 33.318 kB

The folowing keyword changes are necessary to proceed:
#required by sys-boot/grub-9999[truetype], required by sys-boot/grub:2(argument)
>=media-fonts/unifont-5.1.20080914 ~amd64
#required by sys-boot/grub-9999, required by sys-boot/grub:2(argument)
>=media-fonts/os-prober-1.47 ~amd64
#required by sys-boot/grub:2(argument)
>=media-fonts/grub-9999 **

如下图：



纠结了好久了，未果 ！ 求解 ....

unifont-5.1.20080914在~amd分支里
在/etc/portage/package.use里面加上
>=media-fonts/unifont-5.1.20080914 ~amd64

麻烦详细解释下，不是说emerge 可以自动解决依赖吗？ 为什么还得手动 ？
