ld-elf.so.1 borken today?

[walt]

After my morning update today I'm getting this error message from 
certain programs:

ELF interpreter /usr/libexec/ld-elf.so.1 not found.

Well, that's misleading because ld-elf.so.1 is where it should be, and 
has today's
date on it.

ld-elf.so.1.old still works, so recovery is trivial :o)

So, is ld-elf.so.1 really broken, or do I just need to recompile the 
ports (like bash
and cvsup) which don't work with it?
