ruby-opengl-0.60.1-r2 should depend on >=dev-ruby/mkrf-0.2.3-r2, because that version introduces ruby_target ruby19. Reproducible: Always

There is no need for this since this should be handled automatically by the RUBY_TARGETS USE flags. I've just verified that this happens for me when emerging ruby-opengl when the older revision of mkrf is already installed. How did you try to install ruby-opengl?
Simply a rebuild (I think because ruby-1.9 got installed) (using paludis). I have enabled both ruby18 and ruby19. ruby-opengl-0.60.1-r2 has both ruby targets, mkrf-0.2.3-r1 only has ruby18. I retried (downgrade mkrf, reinstall ruby-opengl), and it failed, again, same error.
Adding dagger since this works for me with portage. I'm wondering if this is perhaps a bug in paludis, or whether we are doing something wrong somewhere that portage happens to make work anyway.
Closing this since ruby-opengl-0.8.0 no longer depends on mkrf and there was no further feedback on this issue.
