Hi, The subtle package (a window manager) was blocking the ruby 2.1 TODO list. The build scripts specifically checks for ruby version 1.9. When disabling that check, it has problems linking/compiling and it also does not respect the CFLAGS variable. Tried to patch it with sed, with no luck. If someone wish to give it a stab, it's now in AUR. If it should successfully build and run with Ruby 2.1 in the future (2.1 is currently in [staging]), I would be happy to consider moving it back to [community].
