But Haiku has the soul.
We don't need to clone UNIX all over the place.
Perhaps it’s better to play it safe and just run DOS instead ;)
BeOS on its final commercial version certainly did not allow to compile UNIX applications, beyond the common surface that is part of ISO C and ISO C++ standard library.
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.
