I am still looking at this particular issue, but this is what I think I
have found:

clamav-db (dag) IS a different name ... but the same thing as clamav-
data (kbs).

It also seems that clamd (dag) is the same thing as clamav-server (kbs).

So .. it seems that what is required to make both of these repos to be
enabled at the same time is for dag to add these obsoletes:

In clamav-db:		obsoletes clamav-data
In clamd:		obsoletes clamav-server

and for kbs to add these:

In clamav-data:		obsoletes clamav-db
In clamav-server:	obsoletes clamd

Anyway ... that is what I think I see as the problem ... conformation
anyone?
