Comment(by jlg@…):

 You're right! I looked at 30749, and tried "upgrade outdated" again using
 sudo instead of simply running it as root. The problem does not occur,
 everything works as it should. Very strange. Maybe a sandbox issue of some
 sort.

 On this system, I also notice a bunch of those temp directories in
 /var/folders, which (I'm assuming) must have been left around after
 previous ports that were installed by root, without using sudo.
