You got me interested now.

I just installed the archive-tar-minitar gem and it looks pretty easy to 
generate a tar file, without any patching of the library:

  require 'rubygems'
  require 'archive/tar/minitar'

  src = {
          "foo.txt" => "This is file foo",
          "bar.txt" => "This is file bar",
  }

  File.open("test.tar","w") do |tarfile|
    Archive::Tar::Minitar::Writer.open(tarfile) do |tar|
      src.each do |name, data|
        tar.add_file_simple(name, :size=>data.size, :mode=>0644) { |f| 
f.write(data) }
      end
    end
  end

All I did was a quick poke around the API (gem server --daemon; launch 
web browser pointing at http://localhost:8808/) and look for something 
called "Writer" :-)

HTH,

Brian.
