cairo was involved in Leslie's earlier problem, but it is not involved
in this one -- although the nature of the problem is similar. As I
wrote, now it appears that kdelibs3 is linked with the old png
library, and needs to be removed -- ironically, in order to rebuild
kdelibs3.

That would be one way to prevent a recurrence of this kind of problem
(although not all possible problems) during the remainder of the
update.  Or he could just remove the present offender, and continue
with update, intervening again if necessary.
