def self.use_paths(home, *paths)
  paths.flatten!
  paths.compact!
  hash = { "GEM_HOME" => home, "GEM_PATH" => paths.empty? ? home : paths.join(File::PATH_SEPARATOR) }
  hash.delete_if {|_, v| v.nil? }
  self.paths = hash
end

Use the home and paths values for Gem.dir and Gem.path. Used mainly by the unit tests to provide environment isolation.
