Your bug sounds like your version is depending on an accident of not-quite recent perls. It used to often "just work" to say Carp::croak '...';. That was accidental and whenever you see an exception like this, just make sure to load Carp in advance of loading the thing you're using.

In your example, do:

$ LIST_MOREUTILS_PP=1 perl -MCarp foo
