Apparently I'm the only one with this problem, but maybe someone can
give me a hint:
14.3-RELEASE-p8
DEFAULT_VERSIONS+=python=3.12
Options:
OPTIONS_FILE_SET+=CANBERRA
OPTIONS_FILE_UNSET+=DBUS
OPTIONS_FILE_UNSET+=DEBUG
OPTIONS_FILE_SET+=FFMPEG
OPTIONS_FILE_UNSET+=LIBPROXY
OPTIONS_FILE_UNSET+=LIGHTNING
OPTIONS_FILE_UNSET+=LTO
OPTIONS_FILE_UNSET+=OPTIMIZED_CFLAGS
OPTIONS_FILE_UNSET+=PROFILE
OPTIONS_FILE_UNSET+=TEST
OPTIONS_FILE_SET+=ALSA
OPTIONS_FILE_UNSET+=JACK
OPTIONS_FILE_UNSET+=PULSEAUDIO
OPTIONS_FILE_UNSET+=SNDIO

I had no problem with version 146.0 and earlier.  Thanks for any
clues you can suggest!                                -- George
