If print_help() is what's wrong, you should probably hack print_help() 
instead of sys.stdout.  You could try something like::

     def print_help(self, file=None):
         """print_help(file : file = stdout)

         Print an extended help message, listing all options and any
         help text provided with them, to 'file' (default stdout).
         """
         if file is None:
             file = sys.stdout
         file.write(self.format_help())

     optparse.OptionParser.print_help = print_help

     cmdlineparser = optparse.OptionParser(description=...)
     ...

That is, you could monkey-patch print_help() before you create an 
OptionParser.
