What I am afraid that RubyGems can't distinguish between gems for
Rubinius and MRI as it can't differentiate between binary gems built for
MRI 1.8 or MRI 1.9. For example, for therubyracer gem , you can get
prebuilt gems, but I doubt they can work for Ruby 1.8 and 1.9 as well.
There are "fat binary" gems for Windows (e.g. nokogiri), but that is
more or less workaround, which doesn't scale. RubyGems should support
more than platform to choose the correct gem version.
