I've been rethinking this as someone who spends a lot of time with perl at the command line. I think the reason for suggesting a cleanup on the missing module error is that there's a lot of information and it's a mess. I noticed that everything inside parenthesis looks as if it was hastily added at some point and isn't really necessary. It might be nicer to have perl puke less text upon this error than more: 
Can't locate Super/Duper.pm in @INC
BEGIN failed--compilation aborted.
