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,
