Thanks FunkyMonk. I am familiar with that config option (it is vital!), but it doesn't quite get the functionality I am looking for. I want to run on a currently unpacked, local module. And I don't want it to install the module, just the prereqs. Something like:

$ cd Perl-Critic-xxxx
$ cpanp installdeps .
    Missing prereqs: 
       Config::Tiny
       Module::Pluggable
    Installing prereqs...
    Done.
