killed libc.so.7 somehow - help./ISO images of CURRENT

Hello.
Accidentally, I managed to kill my libc.so.7 and didn't make a backup.
Now my FreeBSD 10/amd64 box, compiled yesterday's world last time,
refuses to do anything since login doesn't work. /bin/sh is missing a
symbol, I forgot the name, it was late last night (and therefore I made
that mistake).

I thought I could start over with a snapshot emergency/live DVD/CD, but
for CURRENT, I can not find any ISO images. Apart from the CTM way, is
there another opportunity toget
a) ISO images of a more recent CURRENT
b) a working libc.so.7 that will make me rebuilding the system?

Sorry for the noise, I'm ashamed about to ask and yes, I will bare the
laugh.
