X Windowing Layer
GIMP uses a separate windowing layer, the X11 windowing protocol, on Mac OS X, which must be installed first. There are various ways to install an X11 protocol window server. The XDarwin project provides this functionality. Apple does provide their own version of this windowing layer, based on XFree86, which is called X11.app. If you do use OS X 10.3, you can grab it from the Apple downloads site. 10.4 users will find it on the Tiger DVD installer disk.
Graphics libraries and toolkits
Unlike most Linux distributions, Mac OS X does not come with the open source libraries upon which GIMP is built. These are typically installed along with GIMP, but can be installed separately. GTK can be built and installed via the various package management systems mentioned above: Fink, DarwinPorts, OSXGNU and others. A complete list of the libraries necessary for a build of GIMP is given in the main source distribution.
