Given that ruby-interpreter is listed as an alternative to ruby,
anything that provides ruby-interpreter needs to have at least all
the binaries from ruby. The harder part is actually having these
binaries work with the libraries that depend on ruby-interpreter.
(They are installed into shared and/or versioned directories and may
ship .so files.)

I do not think it is feasible today to ship a ruby implementation
that provides ruby-interpreter without (some form of) support in

Best is probably to just drop the Provides in jruby.
