3.setup.rb problems and possible fix

As I reported earlier there seems to be some issues with setup.rb.
After investingating deeper it appears that there may be some very odd
bugs lurking within. There's is a lot of good code in their, but I'm
starting to think it may need a fresh rewrite. Of course, it doesn't
help that Minero whas not responded to my emails, and appearnetly does
not frequent this list.

The issue I'm currently facing is that setup.rb does not seem to be
handling --prefix correctly. While most things get the prefix, the lib/
directory does not. Looking at the code one sees these relavent pieces.

  def install_dir_lib(rel)
    install_files libfiles(), "#{config('rbdir')}/#{rel}", 0644
  end

  def install_files(list, dest, mode)
    mkdir_p dest, @config.install_prefix
    list.each do |fname|
      install fname, dest, mode, @config.install_prefix
    end
  end

  def mkdir_p(dirname, prefix = nil)
    dirname = prefix + File.expand_path(dirname) if prefix
    $stderr.puts "mkdir -p #{dirname}" if verbose?
    return if no_harm?

    # Does not check '/', it's too abnormal.
    dirs = File.expand_path(dirname).split(%r<(?=/)>)
    if /\A[a-z]:\z/i =~ dirs[0]
      disk = dirs.shift
      dirs[0] = disk + dirs[0]
    end
    dirs.each_index do |idx|
      path = dirs[0..idx].join('')
      Dir.mkdir path unless File.dir?(path)
    end
  end

Looking at this code one would expect that @config.install_prefix would
hold the value of the --prefix command line option. But oddly it does
not --I'm almost inclined to think that this is unintended in itself.
But assuming that's not how it's supposed to be, then obviously
config('rbdir') must contain the prefix. But it doesn't. The other
similiar config dirs do, config('bindir'), config('datadir'), etc. But
not 'rbdir', which leads me to think that it should actually be
'libdir'.

P.S. Although I've now subscribed to the RubyGems mailing list and
posted my simple solution to the datadir problem, no one has responded
whatsoever.

4.setup.rb metaconfig

Anyone have a real iusecase of setup.rb's "metaconfig" ability? I'm
curious as to how useful this capability really is.

Thanks,
