The version number for libXaw3d changed in XFree86 4.0, which
        breaks the PLIST.

	We can extract SharedXawRev from ${X11BASE}/lib/X11/config/X11.tmpl
	and use that to substitute in the PLIST, but it feels untidy.

	What do people think of the following (tested under XFree86 3.3.6
	and 4.0.1)
