MacPorts update to v21.0.3 causes "Syntaxfehler beim unerwarteten Wort `;'"

Created by: stefanscheidt

I'm using OS X 10.8.2 with MacPorts 2.1.2 and bash version 4.2.39(2)-release. In my .bashrc I do this:

if [ -f /opt/local/etc/profile.d/autojump.sh ]; then
    . /opt/local/etc/profile.d/autojump.sh
fi

I just did a port update of autojump to version 21.0.3, and now opening a new terminal session causes

-bash: PROMPT_COMMAND: Zeile 0: Syntaxfehler beim unerwarteten Wort `;'
-bash: PROMPT_COMMAND: Zeile 0: `update_terminal_cwd;  ; { [[ "$AUTOJUMP_HOME" == "$HOME" ]] && (autojump -a "$(pwd ${_PWD_ARGS})"&)>/dev/null 2>>"${AUTOJUMP_DATA_DIR}/.autojump_errors";} 2>/dev/null'

(Sorry for the german output ...) I have no idea what I'm doing, but changing line 62 in /opt/local/etc/profile.d/autojump.bash from

case $PROMPT_COMMAND in
    *autojump*)    ;;
    *)   export PROMPT_COMMAND="${PROMPT_COMMAND:+$PROMPT_COMMAND ; }$AUTOJUMP";;
esac

case $PROMPT_COMMAND in
    *autojump*)    ;;
    *)   export PROMPT_COMMAND="${PROMPT_COMMAND:+$PROMPT_COMMAND}$AUTOJUMP";;
esac

seem to fix the problem for me. So I suspect the issue is cause by this line

    *)   export PROMPT_COMMAND="${PROMPT_COMMAND:+$PROMPT_COMMAND ; }$AUTOJUMP";;

in autojump.bash.
