You can do something like this:

platforms :ruby do
  gem "sqlite3-ruby", :require => "sqlite3", :group => [:development, :test]

platforms :jruby do
  gem 'activerecord-jdbc-adapter', :require => false
  gem "jdbc-sqlite3", :require => false
end

Btw, you should put your Gemfile.lock into the version control because this way all machines will run the application with the same gems versions.
