[Mailman-Users] Mandriva Upgrade Woes (as Usual)

Well, as usual, my upgrade of Mandriva to v 2010.0 has broken Mailman. I
once again humbly request help. Here is the traceback from 'mailmanctl
start':

/usr/lib/mailman/Mailman/Utils.py:32: DeprecationWarning: the sha module
is deprecated; use the hashlib module instead
import sha
Traceback (most recent call last):

Thanks. Sigh!
