MacPorts

MacPorts Publisher's Description:
The aim of the MacPorts project is to develop a second-generation system for the building, installation and management of third party software.

MacPorts is probably best described by comparison: It's sort of like the FreeBSD ports collection or Fink in that it automates the process of building third party software for Mac OS X. MacPorts also tracks all dependency information for a given piece of software. In other words, it knows what it needs to build and install and in what order for the piece of software you want to work properly. MacPorts knows how to make, build and install the software to a specific location, meaning that software installed via MacPorts doesn't simply scatter itself all over the system or require user knowledge of dependencies in what order.

What's new in this version:

If you already have MacPorts installed and have no restrictions to use the rsync networking protocol (tcp port 873 by default), the easiest way to upgrade to our latest available release, 1.5.2, is by using the selfupdate target of the port(1) command. This will both update your ports tree (by performing a sync operation) and rebuild your current installation if it's outdated, preserving your customizations if any.
