I am trying to install Data::Dump::Tree:

$ zef install Data::Dump::Tree

Here is the complete output from zef:

My Perl 6 version:

$ perl6 --version
This is Rakudo version 2017.09-458-gcf1673d9c built on MoarVM version 2017.09.1-608-ge051ee3c
implementing Perl 6.c.

This isn't a problem in the module but was a transient bug in Rakudo.

It's a good idea to use releases instead of random dev commits—this bug never made it into a release because releases get more thorough testing.
