Pkgng and pc-metapkgmanager/9.2
(Sorry for the inconvenience)
Beginning in February, 2013, PC-BSD® switched from the traditional FreeBSD ports system to pkgng, the next generation package management system for FreeBSD.
All of the PC-BSD® utilities that deal with installing or updating software now use the pkgng system. This allows users to safely install non-PBI software from the command line without that software being deleted by a system upgrade.
Since FreeBSD does not have an official pkgng repository yet, the PC-BSD® project provides its own repository containing all of the packages that can be built using pkgng.
PC-BSD® provides a custom command, pc-pkg which is a small wrapper to pkg in order to improve its functionality. When pc-pkg is used with the install or upgrade flags, it will automatically connect to the use PC-BSD® pkgng repository using the integrated aria2 downloader utility, which can significantly reduce download speeds over a slow link.
