Then you should: 1) add App::cpanoutdated as a dependency for App-ucpan, so CPAN clients install it automatically when user installs App::ucpan; 2) check whether App::cpanoutdated exists on the system and prints an error message when it does not.
Since you do not have 1) nor 2), users will be confused when they try ucpan.
