/bin/tar: Exiting with failure status due to previous errors

The issue is that when tar is run as root, it tries to preserve file ownership when untarring, and in a docker container you're pretty much always running as root.

I think the fix is to simply pass the --no-same-owner flag to tar, but I'm not sure that flag is available on all platforms.

Just speaking for the Docker part here, but I do not see the same issue:

I don't remember what image I was using, but I'm guessing it was either ubuntu:16.04 or centos:centos6.9.

It's not a docker issue so much as a running as root issue, but I doubt folks run cpanm as root outside docker much (or at least I hope).
