3. What is CPAN::Packager?
A tool to help you make Redhat
or Debian packages from perl
modules on CPAN

4. Motivation
• It’s very time wasting to install Catalyst,
Plagger... a LOT of dependencies
• different module versions on each server....
• Can’t make packages because XXX module
has a LOT of DEPENDENCIES...
Make RPM/Deb packages
and manage them with packaging system

5. The problem
• cpanflute2, dh-make-perl
• Don’t resolve module’s dependencies
• CPANPLUS::Dist::{Deb, RPM}
• resolve module dependency at first level
only
• can’t fix incorrect module’s dependencies
manually

6. Packaging System requirements
• Resolve module’s dependencies
• Can fix incorrect module dependencies
manually
• fix module’s incorrect dependencies with a

• Can skip moduledependenciesmodule has
some incorrect
build if the
