use NPH(non-parsed-header) CGI.

rename 'your-script.cgi' => 'nph-your-script.cgi'
and CGI#out({'nph'=>true})

nph-sample.cgi:
  #!/usr/local/bin/ruby
  require "cgi"
  cgi = CGI.new
  cgi.out( 'nph'=>true, 'type'=>'text/plain', 'Last-Modified' => Time.now ) {
    ENV.sort.collect {|k,v|
      "#{k}:#{v}\n"
    }.join
  }
