You are using the following deprecated options: WITHOUT_IPV6
If you added them on the command line, you should replace them by
WITH="" WITHOUT="IPV6"

If they are global options set in your make.conf, you should replace them with:
OPTIONS_UNSET=IPV6

If they are local to this port, you should use:
lang_python27_UNSET=IPV6
