 I cannot reproduce this.  Please put the *compressed* full output,
 both stdout and stderr, available for download somewhere.  Please
 also show me the exact command that you use to build world, and
 the contents of your /etc/make.conf file, as well as the output
 from ``uname -a''.  Please also make sure that you build with an
 empty /usr/obj.
