problem with ld-elf.so.1 install

I just upgraded from -current as of January 31st to -current as of February
13th.

I'm getting core dumps in random binaries.  It's not consistent, but does
happen occasionally.  e.g.:

Since it blew up in ld-elf.so.1, I figured I'd look there...

When I did the installworld, though, ld-elf.so.1 didn't seem to get
upgraded.  (See the January 31st date below.)  But when I tried to install
it manually, the install didn't fail, but didn't work either:

[ looks like we have an old binary, for some reason ]

Anyone have any ideas on what I'm doing wrong here?

Thanks,
