I think your package is the first one that has to actually compile
something, and that supports more than one Ruby version. At least I don't have
one with C parts :-)

It wasn't implemented AFAIK, but perhaps we should try to get different
versions to compile on "build", and then install them all in "install".
But it probably won't be easy to do, because I don't know how to tell if
we need to compile something. Perhaps we could just always use
version-dependent directories. Is there any way to tell setup.rb to compile
things in another directory or something like that?
