Fedora Core 1 Hosed by Failed Yum Update

Any idea (other than a complete distribution reupgrade) how I can
recover?

Atter doing a yum update a couple of days ago, when I run yum I get:

Traceback (most recent call last):
  File "<string>", line 1, in ?
  File "/usr/lib/python2.2/ftplib.py", line 46, in ?
    import socket
  File "/usr/lib/python2.2/socket.py", line 41, in ?
    from _socket import *
ImportError: /lib/libssl.so.4: undefined symbol: krb5_cc_get_principal

I've tried reinstalling krb5-lib and python to no avail.

Thanks.
