Weirdness with sdl in xcode

Hello, I installed the sdl packages in Mac OS X 10.3.4 and whenever I
start a new sdl project within Xcode 1.5, the only thing that shows up
when I open any of the sdl related files included in the project is a
bunch of foreign text; like Japanese mixed with weird symbols.

I also get hundreds of errors when trying to build any example program.
Does anyone know what’s going on here or how to fix this??

Thanks very much for your time,
kurt
