If you have a user-definable fetch function (or abuse another phase for that
purpose) than you can do svn checkouts in your packages. This is easy to do and
supported in Gentoo. For example, you can install all of KDE-4 head from svn via
packages if that's what you want.

Anyway, everything that Alaric explained also holds for Gentoo.
