Gentoo

Gentoo (gentoo.org) is a Linux distribution based on the Portage package management system, which compiles packages from source code rather than installing binaries. This allows software to be optimized to the machine on which it is installed. It supports either a Gnome or KDE desktop and packages can be customised by the use of 'use' flags. For more information see the Gentoo web site or Wikipedia
