Sit down and do the work needed to get Ruby running properly on Haiku instead of sitting here complaining and basically admitting that you're just being a noisy spectator... On HackerNews, no less.
What doesn't work about it? We have Ruby in the software repositories, and Ruby is required to build WebKit (and we build WebKit on Haiku), so clearly it works for that much at least. I don't see any open tickets at HaikuPorts about bugs in the port, either.
Then again, there is a golden opportunity to become a Ruby contributor, road to fame on Ruby contribution list.
