----------------------+-------------------------------
 Mojave 10.14.6, MacPorts 2.6.2
 App store upgraded my Xcode to 11.2 (11B52), and I subsequently did a
 selfupdate and upgrade outdated.

 The build of nodejs10 hung, with two make processes and a constantly
 cycling series of clang processes.  I stopped it by killing the secondary
 make process, leading to the attached log.
