Yep, I think there was a post about setting up IPv6 correctly on HN a while back. Alternatively, you can make your host not respond to IPv6 at all.
If I remember correctly, the problem isn't that IPv6 needs to be set up, but that if your host listens on IPv6, Google will default to that and then your SPF/DMARC/DKIM setup needs to work with IPv6. If you don't have an external IPv6 address, then you don't need to configure SPF etc... for IPv6 and you should be fine.
