Subject: | Add Tk::MMutil to configure_requires |
To prevent installation problems like this one http://www.cpantesters.org/cpan/report/675d068e-ab06-11e4-a5fc-53b5dfbfc7aa (i.e. if Tk::ExecuteCommand is about to be installed before Tk), META.yml's configure_requires list should contain Tk::MMutil.
