upgraded libc6 and libc6 and broke my system (Woody)

[Pollywog <pollywog@shadypond.com>]

Watch out folks.  I upgraded libc6 and libc6-dev and my system is kind of
broken and I don't know if I can fix it.  I downgraded the two packages but I
don't believe things are really fixed:

/var/lib/dpkg/info/libc6.postinst: ldconfig: command not found
dpkg: error processing libc6 (--install):
 subprocess post-installation script returned error exit status 127
dpkg: dependency problems prevent configuration of libc6-dev:
 libc6-dev depends on libc6 (= 2.1.3-13); however:
  Package libc6 is not configured yet.
dpkg: error processing libc6-dev (--install):
 dependency problems - leaving unconfigured
Errors were encountered while processing:
 libc6
 libc6-dev

running dpkg --pending --configure ...
dpkg: `ldconfig' not found on PATH.
dpkg: 1 expected program(s) not found on PATH.
NB: root's PATH should usually contain /usr/local/sbin, /usr/sbin and /sbin.

dpkg --configure returned error exit status 2.

OUCH!!
