File.foreach(lockfile) do |line|
  case line
  when /^  remote: (.*)$/
    sources << $1
  when /^    (\S+) \((.*)\)$/
    gems << [$1, $2]
  end

IO.popen("parallel -j4", "w") do |io|
  gems.each do |g,v|
    io.puts "gem install '#{g}' --version='#{v}' " +

      sources.map{|s| "--source='#{s}'"}.join(" ") +
      " --ignore-dependencies " +
      ARGV.join(" ")
