Darwin
Right so, you've decided you want to play with XML on Mac OS X and/or Darwin and want to use expat.
Basically, grab expat-1.95.1, and not expat-1.95.2, and your life will be considerably happier.
For those of you looking for more info on Mac OS X (Server or otherwise), see ../MacOSX/ for more details (albeit sparse).
