Thanks, Bapt! That is exactly what I was looking for, though with only 210
ports installed, on a system which had a rather broken installation, I
decided to newfs the system and start over. This was clearly the right
choice as several things are now working much better.

It would be great to have this documented somewhere as corrupt databases
are a rare, but real issue.
