I've run into this before, and so in the hopes that this might be useful for somebody else (and for me to remember), let me quickly jot this down here.

This will get you a shiny new NetBSD/EC2 instance in a matter of minutes, but sadly EC2 remains an IPv4-only environment. In order to get your instance onto the IPv6 internet, you will need a tunnelbroker. I happen to like Hurricane Electric's Tunnelbroker service, so the information on this page is based on their configuration.
Once you log in at tunnelbroker.net, follow the link to "Create Regular Tunnel" to get to this page:
Here, you enter the public IPv4 address of your newly created instance. Select a suitable geographical location for your tunnel server and continue. You should end up with a configured tunnel looking like this:
Now, to configure your instance, select the "Example Configurations" tab, and pick "NetBSD/Mac OS X":
Now this is the part where I've made the mistake of following HE.net's directions literally. Their configuration commands are entirely correct, given what they know: the IPv4 address of the host in question would have to be configured for the tunnel device, but: EC2 uses NAT for their instances, and so your actual IPv4 address on your VM is an RFC1918 address, so you need to substitute that address. That is, you'd end up running:
# ifconfig gif0 create # ifconfig gif0 tunnel 10.195.122.108 22.214.171.124 # ifconfig gif0 inet6 2001:470:1f06:1a3::2 2001:470:1f06:1a3::1 prefixlen 128 # route -n add -inet6 default 2001:470:1f06:1a3::1 add net default: gateway 2001:470:1f06:1a3::1 #
With that, you should be in business:
