That's the way to do it. It works today, but the installer isn't smart
enough to pick the right gem yet. It should be trivial to add. Just
hasn't been done yet.
In testing this, I realized that if you do something like:
gem -Ri a
It won't ask you which matching gem to install. It just matches /a/
and installs it. Need to push this onto the TODO list (perhaps after I
wake up this morning). :)

As I said, I don't think it will be too difficult. We need to figure
out how to best match platforms (i686-linux, i586-linux, etc.) so that
the slight ambiguities that exist don't make things unwieldy. But you
can definitely make platform-specific gems now and they should work.
