Hi George,

	The Macports version of xetex is built 64-bit, but it does not have ATSU features.
	so it is not "fully" functional.

	The question is if there is an actual need to still support ATSU at all?
	If we do the question is how hard would be to rewrite the needed libraries.

	If this is the wrong place to discuss this, please point me in the right direction.
