Don't sweat it. It's just because XFree86-libs has (for some I-am-sure-it's-sane-but-it-seams-bone-headed reason) been renamed to libxfree86. Just install XFree86-xfs with a no-deps and carry on like nothing happened...
So the dependancy should be updated to use this file. And libxfree86 is now at version 4.3-20 while all others are at version 4.3-21.
