[Yum] error after install

[anner at blast.com (Anne Ramey)]

installed fine, but now I'm getting:

Traceback (most recent call last):
   File "/usr/bin/yum", line 6, in ?
     import yummain
   File "yummain.py", line 25, in ?
     import cli
   File "cli.py", line 39, in ?
     from yum import pgpmsg
ImportError: cannot import name pgpmsg

any time I try and use it.  I have fedora core 3, with python 2.3 and 
rpm 4.3.2
