Just because people never seem to mention it, I will also throw in a good word for Rudix. From their project page (http://rudix.org/ http://rudix.org/): Rudix features a world class collection of pre-compiled and ready to use Unix compatible software which are not available from a fresh installation of Mac OS X but are popular among other Unix environments. Here you can find utilities, programming languages, libraries and tools delivered as standard Mac OS X packages. The packages are pre-compiled dmgs, easily downloaded and installed, or you can download the whole suite if you prefer. The nice thing here is that if you only want coreutils and you don't want to install Xcode to get gcc, you don't have to.
