I don't think pkgsrc can be configured to use only IPv4. This is an
issue with your OS, which I guess is NetBSD. I think there is/was a
longstanding bug (probably fixed in -current by now) by which NetBSD
doesn't switch to ipv4 when ipv6 is not available, see:
https://mail-index.netbsd.org/port-amd64/2018/02/27/msg002670.html

Otherwise, you need to give more context.

I also see errors about ftp not understanding https address. Maybe using:

FETCH_USING?=wget
or

FETCH_USING?= curl
