{site,vendor}-specific.rb have no meanings in ruby19

[nobu@…]

You can use --vendor command line option instead.

Or, if you prefer to keep the present way, site-specific.rb and vendor-specific.rb should be:

require 'mkmf'
$configure_args.delete('--vendor')

and

require 'mkmf'
$configure_args['--vendor'] = true

respectively.
