This is a collection of SDL support libs which was put together by 
Gabriele Greco from here:-

http://ggreco.interfree.it/sdl.html

Contents:-

SDL_Image :-  by Sam Lantinga and Mattias Engdegard
libjpeg   :-  Independent JPEG Group
libpng    :-  Andreas Dilger & Glenn Randers-Pehrson
libz      :-  Jean-loup Gailly and Mark Adle

 
I have personally used this set of libs to successfully compile a number
of packages.
