Once ruby20 has caught up I think we'll move to a default of RUBY_TARGETS="ruby20" > In spite of that, portage often insists on installing other versions of > ruby, rdoc, rubygems, and you already know the others. Partially this was because we tried to solve another issue when ruby20 went stable. I removed those forced use flags for ruby20 last week, so this should no longer happen. We still need to come up with a good plan when the same issue will pop up for ruby21. > AFAICT, the other versions of ruby are dragged in by old ruby packages > that were installed before I started using "RUBY_TARGETS" (because I > didn't yet know about RUBY_TARGETS), Yes, these will still have other ruby targets recorded and thus also request them for their dependencies. emerge --newuse should be able to help here. > I discovered all of this by grepping for ruby in /var/db/pkg but it took > me a long time to get it sorted out, and I don't expect that a gentoo > beginner could do it. (OTOH maybe a gentoo beginner wouldn't care about > installing multiple ruby versions :) We try to keep the default settings so that someone who doesn't care or know about ruby should get a good experience. Moving from ruby18 to ruby19 we did some things that could have been handled better (such as not mentioning that the new ruby must be eselected before making the switch), so hopefully we've learned from those when we do the next update.
