Subject: Windows cgihandler Error: Premature end of script headers

I've downloaded and installed Ruby (v1.8.5) w/the latest Windows
installer and am trying to run some cgi's per these examples:
http://microjet.ath.cx/webrickguide/html/CGIHandler.html

I keep getting HTTP 500 - Internal server error, and in the Ruby command
line PREMATURE END OF SCRIPT HEADERS.

I've got the path to the Ruby executable in test.cgi, and the next line
outputs a valid header, and this cgi will execute correctly when run by
Webrick directly.  Programs are below.


test.cgi:
#!g:\ruby\bin\ruby.exe
print "Content-type: text/plain\r\n\r\n"
ENV.keys.sort.each{|k| puts "#{k} ==> #{ENV[k]}"}

cgi_handler.rb:
require 'webrick'

include WEBrick    # let's import the namespace so
                   # I don't have to keep typing
                   # WEBrick:: in this documentation.

def start_webrick(config = {})
  # always listen on port 8080
  config.update(:Port => 8080)
  server = HTTPServer.new(config)
  yield server if block_given?
  ['INT', 'TERM'].each {|signal|
    trap(signal) {server.shutdown}
  }
  server.start

end

#start_webrick(:DocumentRoot =>
"g:/infoproweb/webfolder/cgi-bin/ruby",:CGIInterpreter =>
"g:/ruby/bin/ruby.exe")
start_webrick(:DocumentRoot => "g:/infoproweb/webfolder/")


start_webrick {|server|
  #cgi_dir = File.expand_path('~/cgi-bin/ruby')
  cgi_dir = "g:/infoproweb/webfolder/cgi-bin/ruby"
  server.mount("/cgi-bin/ruby", HTTPServlet::FileHandler, cgi_dir,
    {:FancyIndexing=>true})
}
