t/08-taint.t failing with perl < 5.14

[pghmcfc]

My tests on older systems are failing like this:

This is with perl 5.12.4 in Fedora 15. Tests on older Fedoras fail the same way. Tests on Fedora 16 with perl 5.14.3 and later versions pass OK. The perl version may be incidental; perhaps it's some other module that's breaking it?

I saw this with one cpantester report from the last trial but I have been unable to reproduce it. I have no idea what's going on. Any information you can provide would be helpful, for example what line the code is bailing on.

[pghmcfc]

I don't know if this helps. I just typed the following script into perl -Iblib/lib -T after a "make test":

my @expected = qw(
    has_changelog
    has_readme
    has_tests
);
require Test::Kwalitee;
Test::Kwalitee->import(tests => \@expected);

Result on Fedora 16 (working):

On Fedora 15 (not working):

These tests should not be running unless AUTHOR_TESTING=1 and/or RELEASE_TESTING=1!
cannot load Module::CPANTS::Kwalitee::MetaYML: Insecure dependency in require while running with -T switch at /usr/share/perl5/vendor_perl/Module/CPANTS/Kwalitee/MetaYML.pm line 2.

 at /usr/share/perl5/vendor_perl/Module/CPANTS/Analyse.pm line 45

... and the first three lines of /usr/share/perl5/vendor_perl/Module/CPANTS/Kwalitee/MetaYML.pm are:

package Module::CPANTS::Kwalitee::MetaYML;
use warnings;
use strict;

which doesn't look right?

[karenetheridge]

@pghmcfc could you please provide the output of t/00-report-prereqs.t on the system where t/08-taint.t fails? thanks!

[pghmcfc]

@karenetheridge, the info you requested is in the initial report above.

[pghmcfc]

Is there anything I can do to help debug this?

I should be able to provide you with access to a VM exhibiting the issue if that's useful.
