Thanks for that information, Nicolas.

The problem has only happened twice in 4 hours this morning.  Just for luck I have
done "kbuildsycoca4 --noincremental" manually.  That clears the cache and starts
again.  I still got similar error messages, but I am disregarding them for now.

When I did my last upgrade, it was during resolution of an issue among the
MacPorts developers about kerberos5 and friends.  Not knowing about that at the
time I was building, I worked around the build errors, but ended with some broken
kdegames4 apps.  After I uninstalled and re-installed kdegames4, they were OK.

If I have any further problems, maybe I will uninstall and re-install all my KDE ports.

Thanks again, Ian W.
