I think the obvious answer to the question would be: is that in the libsdl portfile? If so then he's using it. If not then he's not. (And it's not.) And equally obviously, if there is a change you believe needs to be made in the libsdl port, won't you file an issue for it in the issue tracker? Thanks.
