    ENV.prepend_create_path "PERL5LIB", libexec/"lib/perl5"

    resources.each do |r|
      r.stage do
        system "perl", "Makefile.PL", "INSTALL_BASE=#{libexec}"
        system "make", "install"
      end
    end

    system "perl", "Makefile.PL", "INSTALL_BASE=#{libexec}"
    system "make", "install"

    (bin/"carton").write_env_script("#{libexec}/bin/carton", PERL5LIB: ENV["PERL5LIB"])
    man1.install_symlink libexec/"man/man1/carton.1"
