Unrelated to this, to recover:

Boot single user (wiht a boot menu, or drop to boot prompt and 'boot-s')
export PATH=/rescue
mount -a # so it's read-write /
this provides ifconfig, route to connect to the internet, and ftp and
tar to unpack a new base.tgz.



Most likely, you had:
libc.so.12.207, libc.so.12.208
From unpacking older sets, you gained a symlink to an older minor:
libc.so.12 -> libc.so.12.207
Postinstall apparently sees, "old minors! I can get rid of it!"

It should probably check that it's not in use.
