Re: LD_PRELOAD=lib using ldopen: can't resolve symbol '_dl_open'

Hopefully, this is caused by the nice mix of libc5/libc6 libraries I'm
forcing bash to use now: ./libfoo.so.0.0 was libc6, whereas bash
is (still) libc5 on my system. I'll _have_ to get that new
bash, but alas, master is still down (and I don't have those new 
libreadline's yet).

Sorry for this on debian-user, but I didn't realise this was libc6
related.
