Pinto is a robust tool for creating custom CPAN-like repositories of Perl modules. You can fill your repository with any combination of private and public modules, and then build/test/install them using the standard tools (e.g. cpan, cpanm, cpanp). Since you control the repository, you'll get exactly the same modules every time. Pinto also has some novel tools for tracking and managing changes, so you can upgrade modules with confidence and control.
