## Chapter 4 Installing Applications using NetBSD's pkgsrc framework 


## Synopsis 

DragonFly is bundled with a rich collection of system tools as part of the base system. However, there is only so much one can do before needing to install an additional third-party application to get real work done. DragonFly utilizes NetBSD's pkgsrc framework ([pkgsrc.org](http://www.pkgsrc.org/)) for installing third party software on your system. This system may be used to install the newest version of your favorite applications from local media or straight off the network.

After reading this chapter, you will know:


* How to install third-party binary software packages from the pkgsrc collection.


* How to build third-party software from the pkgsrc collection.


* Where to find DragonFly-specific changes to packages.


* How to remove previously installed packages.


* How to override the default values that the pkgsrc collection uses.


* How to upgrade your packages.
