[gentoo-user] emerge a binary package no longer in tree

[Raffaele Belardi]

I'd like to try and update a package I masked long time ago due to performance problems. 
Upstream the problem does not seem completely addressed and solved so I'd like to be able 
to go back to the old version just in case. But the old version is no longer in the tree. 
If I quickpkg it will I be able to reinstall it anyway?

thanks,

raffaele
