Ah, got it. IO::Socket::INET6 is not installed on this system. I build
RPMs of dnscheck, and RPM is generally clever at figuring out all the
dependencies of a package. However, IO::Socket::INET6 is not a direct
dependency of dnscheck, but an indirect one by way of Net::DNS::Resolver.

Grr. This is annoying. I will adjust my RPM spec file and list the
dependencies explicitly, and repeat this test. I'll let you know how it

Thank you for the pointers!
