Hi, I'm trying to build the gem on my local workstation to create a native arch linux package. during the test run I get the above issues. If I remove my IPv6 resolver from /etc/resolv.conf the tests pass. Any idea how to fix this?

Probably has something to do with the fact that Coolio::DNSResolver doesn't support IPv6.
