I have tried to install it to my computer. It fails with:

Could the multiple times; be the culprit?

Anyway, if you want to switch to ExtUtils::MakeMaker, then here is a basic Makefile.PL:

use 5.006;
use strict;
use warnings;
use ExtUtils::MakeMaker;

WriteMakefile(
#EDIT: only for testing
#INSTALL_BASE => 'xxx',
    NAME             => 'Graph::Undirected::Hamiltonicity',
    AUTHOR           => q{XXX <XXX@cpan.org>},
    VERSION_FROM     => 'lib/Graph/Undirected/Hamiltonicity.pm',
    ABSTRACT_FROM    => 'lib/Graph/Undirected/Hamiltonicity.pod',
    LICENSE          => 'artistic_2',
    PL_FILES         => {},
    MIN_PERL_VERSION => '5.006',
    CONFIGURE_REQUIRES => {
        'ExtUtils::MakeMaker' => '0',
    },
    BUILD_REQUIRES => {
        'Test::More' => '0',
    },
    PREREQ_PM => {
        # add here dependencies
        #'ABC'              => '1.6',
        #'Foo::Bar::Module' => '5.0401',
    },
    # it adds your scripts too in bin/
    EXE_FILES => [ glob("bin/*.pl") ],
    dist  => { COMPRESS => 'gzip -9f', SUFFIX => 'gz', },
    clean => { FILES => 'Graph-Undirected-Hamiltonicity-*.gz' },
);

In order to make a tarball for export to CPAN, then do: perl Makefile.PL && make && make manifest && make test && make dist

Warning: I am seriously cargo-culting with the above so there can well be a better/safer way.
