DDD 3.3.12 (arm-apple-darwin22.4.0) gets Xt error (installed from source via MacPorts)

[Kenneth Wolcott]

Hi;

  I installed (from source) the ddd port from MacPorts.

  I'm on a Mac Mini running Ventura 13.3.1 (M1 chip).

  I'm using Xquartz (from MacPorts).

  All I did was "ddd return".

  Here's the contents of the ~/.ddd/log file:
