No.  Let me know if you'd like me to do something.  It sounds as if you
guys may have figured this out already, but I'll give you what info I
have.

Yes.  In answer to a question in a later message, the logs show
2008-11-27 09:57:26 status installed xml-core 0.12
2008-11-27 10:11:58 status installed docbook-xml 4.5-6
being updated at the same time.

when run as root.  BTW, it is not clear to me what this command does
from the xmlcatalog man page; I guess it's a check of some sort.

I don't know much about the machinery behind this, but if I understand
the exchanges so far, the theory is that because xml-core and friends
were being updated a reference, that would normally be found locally,
was not found.  The result was an attempt to retrieve the same thing
from the internet.  However, I don't understand what would have
prevented successful internet access.  I was able to access the location
after the upgrade.  My initial thought was that something needed for
internet access had been shut down during the upgrade; I looked for
relevant packages and listed the only ones that seemed close in my
initial report.  I didn't really see anything that looked as if it could
be responsible.

Another possibility is that the network, most likely my local wireless,
flaked out for a while.  However, I haven't noticed such behavior
generally.

I'll switch to rarian-compat; is there some reason to think it won't
exhibit the same problem?

Thanks to both of you for jumping on this.
