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.

So, if we forcibly disable IPv6 support in the system, the smp-server binary does not start at all.
If we leave this setting untouched, everything works as expected.
Maybe this is a subtle hint that soon nothing will work without IPv6 support? :)

that would suck

Updating to confirm 6.4.4 still fails if the underlying system has ipv6 disabled. Is there a way to disable this ipv6 requirement when compiling from source?
