@ https://wiki.gentoo.org/wiki/Ruby#Upgrades RUBY_TARGETS="ruby22 ruby22" should be RUBY_TARGETS="ruby23" or (for what reason ?) be RUBY_TARGETS="ruby22 ruby23" "Upgrade" sounds like from 22 to 23. IMHO ="22 23" sounds like: keep 22 and additionally support 23.
fixed. thank you
RUBY_TARGETS="ruby22 ruby23" as long as some packages still need ruby22 you can leave it there and drop it later...
I see, thanks for fixing!
