In Windows, you can use this code.  I'm not sure where I found this 
from, so I can't tell you who to thank :P

require 'Win32API'

@uuid_create = Win32API.new('rpcrt4', 'UuidCreate', 'P', 'L')

def new_guid
  result = ' ' * 16
  @uuid_create.call(result)
  a, b, c, d, e, f, g, h = result.unpack('SSSSSSSS')
  sprintf('{%04X%04X-%04X-%04X-%04X-%04X%04X%04X}', a, b, c, d, e, f, g, h)
end

puts new_guid


Cheers,
Mohit.
