Bug 256432: www/youtube_dl: distfile fetch fails over IPv6-only network
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=256432



--- Description ---
MASTER_SITES points to yt-dl.org which has both A and AAAA RRs:

$ host yt-dl.org
yt-dl.org has address 95.143.172.170
yt-dl.org has IPv6 address 2001:1a50:11:0:5f:8f:acaa:177

Dual-stack nodes would fallback to 95.143.172.170 if AAAA failed,
but IPv6-only nodes (with DNS64 or not) can only try AAAA, which 
is unreachable from at least AS8359 and AS207996:

Upstream was notified via e-mail to hostmaster from SOA of zone in April,
no response and no issue resolution since then.

I think switching to USE_GITHUB (DNS64) or mirroring distfile on FreeBSD
cluster
would fix this, until the issue is fixed by yt-dl.org hostmaster.
