could you get it to work to send a SYN packet?

could you test this script:

#!/usr/bin/env ruby

require 'libnet'

$VERBOSE = true

l = Libnet.new

10.times do
    l.build_tcp(31337, 80, rand(2 ** 3), 0, Libnet::TH_SYN, 0, 0, 0, 
Libnet::LIBNET_TCP_H, nil, 0, nil)
    l.auto_build_ipv4(Libnet::LIBNET_TCP_H + Libnet::LIBNET_IPV4_H, 
Libnet::IPPROTO_TCP, "192.168.0.2")
    l.auto_build_ethernet(l.hex_aton("00:11:11:94:D4:F5"), 
Libnet::ETHERTYPE_IP)
    ret = l.write
    l.clear_packet
    puts l.geterror if ret < 0
end

sent,error,written = l.stats
puts ""
puts "Sent: #{sent}"
puts "Error: #{error}"
puts "Bytes Written: #{written}"

# end of file

because it is always segfaulting ruby on my machine :(
