Maybe try

MESON_ARGS+=   -Ddefault_bus=dbus-daemon

to use the dbus daemon that is in pkgsrc?


The commit was

    meson: Use dbus-broker by default
    
    We have a default_bus option in meson that controls whether dbus-daemon
    or dbus-broker will be used in cases where both are available. Trying to
    use dbus-daemon no longer works on one of my systems, and dbus-broker is a
    more sensible default nowadays (the original code making dbus-daemon the
    default dated back to 2018). Hopefully, this change will have no effect on
    non-Linux systems that do not use dbus-broker, and dbus-daemon will continue
    to be used in such cases.

so presumably you are on a Linux system, but then it isn't obvious which
dbus implementation to expect from the above.
