These are Mac OS X frameworks and Unix software for much of the UNIX stuff in my [old] build instructions. While they are aimed at MapServer, GRASS, QGIS and other GIS software, they are intended to be reusable for other software.
Mac OS X 10.6 is the minimum requirement. Current packages are for Snow Leopard and newer. Frameworks support both 32bit and 64bit Macs, but most end-use software is 64bit only. Also, Intel only.
I can help with problems and questions about installation problems and use of my builds of this software. For general use questions, see their respective sites' support resources.
Some notes for developers to make use of the frameworks, and libraries in the other software.
