This document summarizes a presentation about managing CPAN dependencies for web development projects. It describes a case study where a developer installed many CPAN modules for a new web app, but ran into problems with dependency and versioning issues during deployment to production servers. The presenter then introduced their solution called Carton, a tool for creating isolated, local Perl environments for apps and locking dependency versions to allow reproducible, stable deployments across different machines. Key features discussed included dependency declaration, isolated environments, version control, analysis and more. The document concludes with a call for questions and thanks.
