This turns out to be an issue with rubygems. It seems that our operating_system.rb defaults that used to work don't properly allow handling of "default" gems, and irb is now packaged as such a default gem in ruby 2.6.

The old defaults were broken with the introduction of default gems in rubygems 3.0.0. The new defaults should be backward compatible with the old defaults, but they use defined hooks for the most part to do the work.

dev-ruby/rubygems-3.0.3-r1 has rewritten Gentoo defaults that fix this issue. This version is currently masked for testing since the rewritten defaults may break other things. I'd be happy to get feedback on this new version.
dev-ruby/rubygems-3.0.4-r1 contains a fix for this issue and has been unmasked.
