This issue will track the removal of Rubinius from ruby-build, as requested by @brixen, Rubinius’ maintainer, in #860 (comment):
Honestly, given the amount of time I've wasted with rbenv, RVM, and chruby bugs and insisting on telling me how Rubinius should build and package, it would be better if none of them installed Rubinius.
- Remove rbx-* definition files
- Remove Rubinius support functions
