Hey Attached is ri.tgz, it contains a ri-0.7a.ebuild, and a patch to make it install into ${D} (the default script has /usr/ hardcoded) ri is a command line tool to show documentation about the ruby's build in classes, and standard library. I'm not sure where it should be, maybe dev-ruby/ri or app-misc/ri, or app- doc/ri even... I have no idea.
