smp-server start fails on ubuntu without IPv6

[cthulhubuddha]

I have an ubuntu server with IPv6 disabled and smp-server 6.2 fails to start wiith the following error:

smp-server: Network.Socket.socket: unsupported operation (Address family not supported by protocol)

I don't see IPv6 being listed as a requirement in any docs, is this a bug?

Deployment update:
Using prebuilt binary smp-server 6.2
Ubuntu 22.04

/etc/sysctl.conf
net.ipv6.conf.*.disable_ipv6=1

smp-server spins up just fine with the above sysctl.conf settings set to =0 (IPv6 enabled).

Can the prebuilt binary check for ipv6 and not try to run with it if it is disabled?

I didn't see anything in the 6.3.0 change log regarding this, but am confirming after updating to 6.3.0 this is still an issue.
