Among the packages to be upgraded were libLASi (from 1.1.1_0 to 1.1.1_1) and graphviz (from 2.34.0_1+pangocairo+x11 to 2.34.0_4+pangocairo+x11). However, the port upgrade command chose to execute the upgrade in an unfortunate sequence: First it tried to upgrade graphviz, which failed due to the bug in ticket https://trac.macports.org/ticket/41567 -

That was actually not my point.

I just noticed that it was not port upgrade that did the out-of-order install, but rather a "rebuild after database errors". My first port upgrade command ran into bug https://trac.macports.org/ticket/41737 (against webkit-gtk, which appears to be still open). The workaround requires running 
port -f deactivate webkit-gtk
port install webkit-gtk-2.0

The latter command resulted in the following output:

The "repair" job thus tried to rebuild graphviz, without upgrading libLASi beforehand, and thus failed.

I do apologise for my incorrect earlier e-mail; the problem was not with port upgrade, but with whatever it is that checks for broken ports. Please do let me know if this is a bug and I will file a ticket.
