As such, you can specify different features you'd like to include or exclude based on your needs, and, since it's compiled for your system, you should in theory get some performance boost. Although with most programs on a modern system, the increase isn't likely to be very significant. It can also take a very long time to compile a large program from source. Another option is Arch Linux, http://www.archlinux.org/, which primarily uses binary packages, but also has the option to use their Arch Build Tree to compile from source through a PKGBUILD script, similar to Gentoo's ebuild scripts. There is also the Arch Users Repository, which is a collection of unofficial PKGBUILDs created by the community. [Modified by: Reed on February 13, 2009 02:46 PM]

Portage then downloads and untars the sources and runs configure,make & make install. Packages which can be configured on build time (eg. to remove/add features, such as optional codec support for media players, or gui frontends in qt/gtk) are handled by so called use-flags which are simple keywords you can set or unset. When finished portage merges the compiled result into the system watching for filename collisions (colliding config files mostly on updates) and lets you merge that files interactively.

That I think portage is much slower then using deb. So I'm a much of a debian distro user. I stay away from any Gentoo distro. That's just my two cent worth.

Of course portage is slower than deb, or yum, or synaptic (apt-get). Those install already-built binaries whereas portage does a complete build of the software before installing it. However, if it builds successfully, you know that it is built specifically to run in your system. Sometimes real fast is almost as good as real time. Remember, Google is your friend!
