Gentoo Forums :: View topic - GF5: Masked Packages: "GF5: What are masked packages? Packages that will not be installed on your system unless you take specific actions. A package may be masked by placing an entry in /usr/portage/profiles/package.mask. Historically, this was the only way to mask packages. If you wish to install a package that is masked in package.mask, you will need to comment out the mask entry line for that package. Note that package.mask is overwritten by 'emerge sync', so your changes will not persist across a sync. Some workarounds for this can be found in emerge overwrites packages.mask. You can also mask problematic packages by adding entries to packages.mask."
