cpan> install Cwd
Running install for module Cwd
Running make for G/GS/GSAR/perl-5.6.0.tar.gz
 
The most recent version "2.02" of the module "Cwd"
comes with the current version of perl (5.6.0).
I'll build that only if you ask for something like
    force install Cwd
or
    install G/GS/GSAR/perl-5.6.0.tar.gz
