  I'm getting a consistent error with cvsup from this morning during
make installworld


libexec/rtld-elf
install -s -o root -g wheel -m 555  -fschg -C -b ld-elf.so.1 /libexec

I've done make cleandir and re-cvsup etc. Same error.
amd 2400 asus mb. running cvsup/makeworld  almost daily for
4 months with minimal problems.

Probably something simple I just don't see.

cheers,
