MISSING PREREQUISITES:

It was observed that the test suite seem to fail without these modules:

$modules

As such, adding the prerequisite module(s) to 'PREREQ_PM' in your
Makefile.PL should solve this problem.  For example:

WriteMakefile(
    AUTHOR      => '$author',
    ... # other information
    PREREQ_PM   => {
$prereqs
    }
);

Thanks! :-)

RECOMMENDATIONS:

It would be very helpful if you could include even a simple test 
script in the next release, so people can verify which platforms
can successfully install them, as well as avoid regression bugs?

A simple 't/use.t' that says:

#!/usr/bin/env perl -w
use strict;
use Test;
BEGIN { plan tests => 1 }

use Your::Module::Here; ok(1);
exit;
__END__

would be appreciated.  If you are interested in making a more robust
test suite, please see the Test::Simple, Test::More and Test::Tutorial
documentation at <http://search.cpan.org/dist/Test-Simple/>.

Thanks!  :-)
