problem building swt-devel

[Robert Huff]

	[I've mailed the maintainer, java@, and ports@, and had either
no response or one which didn't help solve the problem.
	questions@ is my last, best hope .... ]

	On a system running:

FreeBSD 10.0-CURRENT #0: Sun Dec 30 12:52:09 EST 2012  amd64 

	I am trying to build x11-toolkits/swt-devel as a dependency for
another port.
	If I compile using clang, I get:

	I re-installed www/libxul, and nothing changed.

	Receimination phase - if any - will happen after this gets
fixed.
	Help, please!

	Respectfully,
