That's right.  The gem build command uses various conventions to avoid
gems of the same name and different platforms clobbering each other. 
But the actual selection of gem to install based on platform uses the
gem's metadata--not it's name.  So you could have an fxruby gem named
blah.gem, and it would still get it's platform _and_ name from the
gemspec.
