IPv6: getsockaddrarg() takes exactly 2 arguments (4 given)

[ihmels]

When a hostname is resolved to an IPv6 address, Px does not work and I receive the status code 408. I've set noproxy = 0.0.0.0/0, ::/0 and I get the following error, when I run

curl -I http://packagist.org

Looks like some work was done around enabling IPv6 in a fork: ltauvel@e44302b

Hoping @ltauvel can comment and maybe provide some patches to get this working in Px.
