All this is chatter and manipulation of general opinion.
For about 8-15 years, marketers say that ipv4 is about to end, but ipv4 is not over yet!
And most of the internet segment is on ipv4.
We will use ipv4 for at least another 10 years!
All this is chatter and manipulation of general opinion.
Created a ticket.

I assume that the problem is in the IPv4 address (139.178.72.204).
IPv6 in my system is completely removed, I do not need IPv6.
I will not build the system with ipv6!

well, the internet is for pr0n
LOL again, cause, this might actually happen earlier, don't you think?
I don't think this would apply so much to, well, this specific area

}Is this code in version 0.93 ? Or will be merged in a next release?
no idea; i'm not the port author, nor the maintainer
I just committed this. Thank you very much!
Done!
Nice to know... I'm gonna stick with portsnap for now... even though it's getting deprecated.
Had core dumps from gitup more than once on three machines over the last days. I just fetched the entire ports tree from scratch, and then it worked again.
