Well suggested.  Once I removed the "killall -u macports" in the
Makefiles and broadened the diagnostics, I found the following, which
survived into an interactive session:

$ sudo lsof | grep /opt/local
[snip] 85084           macports    7r      DIR                1,4         96 26913415 /opt/local/var/macports/home/Library

$ ps auxww | grep -i
macports         85084   0.0  0.1  4854824  14384   ??  S     2:27pm   0:01.08 /Library/Developer/PrivateFrameworks/CoreSimulator.framework/Versions/A/XPCServices/

.... Bingo, for sufficiently provisional values of Bing.  Much thought
needed on which of several approaches to take next, and I'll need to
guard against premature rejoicing, but it's the first substative Clue
I've seen yet.  Wish me luck, folks.

PS: There were also odd icon files under /opt/local/libexec/qt5 which
iconserviceagent was holding open (from a console login by sysadmin),
but /opt/local/libexec no longer existed.  I'll worry about whether
that matters later; one problem at a time.
