Writing Configure scripts in Perl

What are the tools I need to get to be able to build configure scipts 
in perl.
I wan't to be able to automatically determine the set of tools avaible, 
and generate
make files for my projects. Some tools generate a shell script, but 
I've seen other open
source packages where the config script is written in Perl.
