Current ruby upgrade from 2.0 to 2.1 reveal at least one issue with dependencies: vim wasn't automatically rebuilt, and neither ruby ebuild nor news warn about it should be done after ruby upgrade. To reproduce this issue: - eselect ruby set ruby20 - USE=ruby emerge vim - install some vim-ruby plugin like Command-T - try to use Command-T within vim: it should work - eselect ruby set ruby21 - recompile Command-T with current ruby - try to use Command-T within vim: you'll get "vim should be compiled with ruby support" error, which can be solved by re-emerge vim Maybe there are other packages which should be rebuilt after ruby upgrade, I didn't check and just in case rebuild everything listed by `equery depends ruby`.
