[CentOS] Lame update from Dag's repo fails for me, any help?

Mon Jan 30 16:39:33 UTC 2006
William L. Maltby <BillsCentOS at triad.rr.com>

Trying yum update for the latest announcements. Part of the problem I
experienced last week appears again: lame library DSA key is
unavailable. I had tried to resolve this last week, to no avail. Tried
again this week and found a French site with the key ID, but for libmad.

Anyone can give me the proper instructions so this works?

TIA
Bill

Here is a snipped part of the yum log.
