This is not relevant.  That's the tests detecting that you don't have
tar installed and thus skipping all the tests that require it.

Here's the details of what's happening in the tests:
  https://gist.github.com/wchristian/dcace83dc70011ae47ca

So I think that these are just warnings and can (for now) be ignored.

The message "failed 9/38 subtests" is a bit misleading. It actually
appears to mean that something is crashing horribly at about line 147 of
this file - there are nine tests remaining to be run at that point:
  
https://metacpan.org/source/DCANTRELL/CPAN-ParseDistribution-1.5/t/fileindexer.t

This makes sense, as trying to parse the Acme-BadExample distribution is
where it tests the magic for having the child process time out.

Here  are several other identical test failures
on various versions of perl on Windows.

ActiveState 5.16.0 ? Why not 5.16.3? Why not S.B.Perl? Re: Timing out a child process on Windows

Hi!

I've factored the Unix-specific code into a separate module now, so if
anyone gets a chance to look at it, it should be easier to fix.
