    def initialize dep_uri = 'https://rubygems.org/api/v1/dependencies'
      super()

      dep_uri = URI dep_uri unless URI === dep_uri # for ruby 1.8

      @dep_uri = dep_uri
      @uri     = dep_uri + '../..'

      @data   = Hash.new { |h,k| h[k] = [] }
      @source = Gem::Source.new @uri

      @to_fetch = []
