I've always thought that it was a bad idea for Linux distros to package any language libraries at all. It seems like a lot of repeated work and your users will probably end up needing to install things manually in the end. Things will require the lastest version of gems, new and essential features will be added, etc. Just give your users a manual on how to install gems (or pip, or whatever) and let it be. The users of language libraries are exclusively programmers after all; I think it's safe to assume they can handle library installation.

That said, Zed is blowing this way out of proportion.
