Perl 6 not ready for public

So, I decided to give Perl 6 another shot and started following the instructions on the Rakudo site. At this point I am close to giving up before I even try the language. The toolchain can't even install the Task::Star modules without throwing (apparently random) errors:

So it failed to install URI, but running it again causes it to install it successfully? And then there are the constant warnings about "Use of uninitialized value %ENV of type Any in string context\nAny of .^name, .perl, .gist, or .say can stringify undefined things, if needed." Then it fails with the a different error and then succeeds after being rerun. So far this is not looking like Perl 6 is ready for the public.
