The Gentoo setup can do this too. It install gems for all supported, desired, ruby implementations, and keeps separate gem hierarchies for each ruby implementation, so you can use different ruby implementations for different applications if you want. This is all part of the ruby-ng.eclass, which all packages in testing use, and which is currently being pushed into stable. Kind regards, Hans
