I think this problem has now gone away on my machine. I cannot be sure what it was that helped. I removed all qt-* packages, and some of the problematic packages mentioned as depending on the earlier versions. After running
# emerge -utv world, I noted some dependencies, and may have removed
one or two. Then I ran the install.
After a couple of interations, all *seems* to be well.
Thank you for the advice,
Alan Davis
