You need to update install.
From src/UPDATING:
20011028:
        src/etc/Makefile now needs install to be able to handle
	symlinks that point to nowhere. A bug in install that
	prevented this was corrected.

	Solution: update and reinstall usr.bin/xinstall
	Better Solution: Use the new toolchain and it will just work
	for you.

The "Better Solution" didn't seem to happen on my i386 machine.
(At the time I ran into this, it may work now, I don't know.)
