-CURRENT buildworld dies

[Robert Huff]

	Running 5.0, I cvsup and build -CURRENT every night.  (Build,
not install.)
	Recently, the buildworld has been bombing with:

	As no one else is reporting this or something similar, I'm
willing to believe it's my screw-up ... but don't understand the
details of the build process well enough to fix.  Are the make files
broken, have I got a missing or excess file, or did mergemaster take
a detour through the Twilight Zone?
