CCing upstream, Alexey, are you aware of this?

Never saw such error, but I now reproduced it with dev-lang/swig-4.1.0

    net-irc/znc: fix build with SWIG 4.1.0 and USE=perl/python
    
    Also always enable IPv6 as it doesn't require additional dependencies
    (pkgcheck warned of "UseFlagWithoutDeps").
