OSX Package Management
derefr:  reason that package management feels so integrated on Linux is that Everything Is A Package, including the system components. This works because, usually, every required for a Linux system is open-source and free-as-in-beer.On OSX, on the other hand, many things that people want to install are closed-source, for-pay apps. Having different installation and management for those than for open-source packages is what makes fink/macports et all feel like ghettos.A "real" package management system for OSX would be more like a package store: it would allow you to install both free and paid apps, and handle upgrading/installing dependencies/uninstalling them equally well. It would also need to be able to detect and "absorb" responsibility for any apps you installed from DMGs.Of course, once such a system was created, Apple would very likely buy it and integrate it with Software Update.
