Masked by missing keyword
This is common if you are attempting to install the application when it has not been tested on your architecture.
If you have a CVS package marked has 9999 you can do the following: echo "media-gfx/retina **" >> /etc/portage/package.keywords
Bear in mind that if you install onto untested architecture for that application, it may not work.
Note: Note that usage of -* (as many people used to use it, atleast) has been obsoleted and it should no longer be used. It has been replaced by **. You may occaisionally come across third party overlays which still use -*. Please petition their maintainers to update them.
echo "sys-boot/grub **" >> /etc/portage/package.keywords
# echo "sys-boot/grub **" >> /etc/portage/package.keywords
# emerge -pv grub
These are the packages that would be merged, in order:

Hard Masked
Hard Masked packages are unmasked by adding them to /etc/portage/package.unmask. The syntax for this file, however, slightly differs from package.keywords:
echo "=app-admin/filewatcher-2.4.0" >> /etc/portage/package.unmask
This would unmask version 2.4.0 of app-admin/filewatcher. If you want to unmask every version of a package, just specify its name like so:
echo "app-admin/filewatcher" >> /etc/portage/package.unmask
Of course, it is also possible to use the < and > operators like in package.keywords.
Note, that a package which has been hard masked is usually marked as unstable as well. You probably have to add the package to both package.unmask and package.keywords.
А почему именно grub-1.96 ?
Только вот возникла еще одна проблема: при установке требует g++ а его у меня нет. Отдельным пакетом g++ в женте отсутствует (думается входит в состав gcc); gcc - стоит (4.1.1) при emerge gcc - снова просит g++. Как быть?
