KDE 3.4.1 - kompmgr build failure

[Li, Qing]

	When I tried to build /usr/ports/x11-wm/kompmgr, the
	build fails in kompmgr.c. When I set X_WINDOW_SYSTEM
	to xfree86-4, the error message I got is
	kompmgr requires composite extensions, which is not
	available in XFree86, and the build exits.

	Has anyone else seen this problem? Is there a way
	to fix it?

	My XFree86 is the binary distribution of 4.5.0.

	I'm running 6-CURRENT.

	TIA
