It seems to me that, logically, you have a repository object that lets you
do things with a repository, and a gem object that lets you do things with a
particular gem. Then I could do things like:

   remote = GemRepository.new("rubyforge.org")
   local  = GemRepository.new("local")

   remote = GemRepository.new("default")

   remote.each { |gem| remote_gems.add(gem) }
   local.each  { |gem| local_gems.add(gem) }

   a_gem = remote_gems[some_gem_name]

   # retrieving gem information

   # performing an actions
   a_gem.upgrade   # upgrade to latest version

Could yield blocks handle this?

   a_gem.install do |uninstalled_dependent_list|
