MacPorts is a powerful tool that enables you to install many common Linux applications on Mac OS X.
- Mac OS X (Tiger or Leopard)
- Xcode Developer Tools (2.4.1 for Tiger or 3.0 for Leopard)
- usually the latest version of X11
Since you can grab GIMP, wget and others from other places on the net you might ask yourself why you should be using MacPorts. The answer is simple: you'll be able to use the latest versions of these applications and customize them as you want. You could for example build a native version of wine (Darwine is PPC so you'll loose speed) or build a native version of GIMP (without X11).
Just give it a try. Installation is not trivial, but you'll love it. Once I have the time I might add some more instructions on this place. I don't know if it is even needed - check the discussion page. .
