Sorry for reviving such a long dead thread, but it is the only thing that 
I've been able to find that seems remotely related. I'm working on a 
project that is using Dir.mktmpdir. I'd like to maintain some backward 
compatibility with 1.8.6 and to that end was thinking of adding something 
simple like:

unless Dir.respond_to?(:mktmpdir)
  def Dir.mktmpdir(prefix_suffix=nil, tmpdir=nil)
    case prefix_suffix
    when nil
      prefix = "d"
      suffix = ""
    when String
      prefix = prefix_suffix
      suffix = ""
    when Array
      prefix = prefix_suffix[0]
      suffix = prefix_suffix[1]
    else
      raise ArgumentError, "unexpected prefix_suffix: 
#{prefix_suffix.inspect}"
    end
    tmpdir ||= Dir.tmpdir
    t = Time.now.strftime("%Y%m%d")
    n = nil
    begin
      path = "#{tmpdir}/#{prefix}#{t}-#{$$}-#{rand(0x100000000).to_s(36)}"
      path << "-#{n}" if n
      path << suffix
      Dir.mkdir(path, 0700)
    rescue Errno::EEXIST
      n ||= 0
      n += 1
      retry
    end

    if block_given?
      begin
        yield path
      ensure
        FileUtils.remove_entry_secure path
      end
    else
      path
    end
  end
end

Just a copy-paste from tmpdir.rb from the lib of a 1.8.7 installation 
wrapped in a respond_to? into one of my project's files. What I want to 
know is how to properly attribute the code in our project from the 1.8.7 
lib? There is no statement in the file, and I can find nothing in the 
installation or several searches with google.

Can't reuse this code unless I can acknowledge where it comes from, please 
let me know how to to this correctly.

Thanks,
