Thanks for your reply!

For  ruby rb/compile.rb /tmp/add.rb
I get the error

rb/compile.rb:17:in `compile_to_rb': uninitialized constant YARVCore (NameError)
        from rb/compile.rb:60
        from rb/compile.rb:57

I don't know whether I should track that down.

If I run ruby-yarv /tmp/add.rb is that the proper invocation? Or is
there a way to get better (faster) results with yarv?
