You need to run the command in the top-level InetUtils build directory.

When InetUtils fail to detect support for IPv6 in the operating system,
InetUtils will not build IPv6 tools.  For your system, I suspect it does
support IPv6 (that is why ping6 was built) but that you haven't
configured a loopback IPv6 interface, so the ping6 self-test failed.

What does 'ifconfig' on your machine output?

If my theory is correct, we could improve things by having the self-test
fail a bit more gracefully.  However, we could also just document that
you need a properly configured system to run the self-tests.
