Description
I get a similar error message to https://bugs.ruby-lang.org/issues/9477
The error message I see:
Errno::EPROTONOSUPPORT: Protocol not supported - socket(2) - udp
Similarly:
$ ruby -rresolv -e 'puts Resolv::DNS.new.getresource("_rubygems._tcp.rubygems.org", Resolv::DNS::Resource::IN::SRV).target'

I am running this in a FreeBSD jail (created by Bastille) that does not have IPV6 connectivity, on a host that does have IPV6 connectivity.
Similar to the previous issue, the problem is successfully resolved by commenting out the IPV6 nameserver lines.
Longer output for reference:

Hmm. The resolver is already catching Errno::EAFNOSUPPORT for this, but I guess Errno::EPROTONOSUPPORT can happen as well (is this a BSD vs linux thing, I wonder?) - see https://github.com/ruby/resolv/blob/b28a2665cd87c4749096ab5201b7d936d4a61d5e/lib/resolv.rb#L753. It seems reasonable to catch both though.
I opened https://github.com/ruby/resolv/pull/41 for this. Thank you for your report!

- Status changed from Open to Closed
Applied in changeset git|02cc9d48f1958e8f22757116358cf5863cb109f4.
[ruby/resolv] Catch EPROTONOSUPPORT as a sign of no IPv6 as well
(https://github.com/ruby/resolv/pull/41)
If IPv6 is disabled inside a freebsd jail, it seems this returns
EPROTONOSUPPORT and not EAFNOSUPPORT. In both cases, we should simply
try some other listed DNS servers.
