[SDL] Mac Os X : SDL-mixer problem

[Dan]

Hi,
I am brand new to SDL and am having problems compiling the sdl-mixer example
code:

Requirements:
You must have the SDL.framework installed.  ***DONE***
To Install:
Copy the SDL_mixer.framework to /Library/Frameworks  ****DONE****

I am using the latest code which stops at:
#include "SDL.h"
#include "SDL_thread.h"
#include "SDL_mixer.h"

It's doesn't like any of these library names:
/Users/danny/sdl_mixer/main.cpp:1:17: error: SDL.h: No such file or
directory
/Users/danny/sdl_mixer/main.cpp:2:24: error: SDL_thread.h: No such file or
directory
/Users/danny/sdl_mixer/main.cpp:3:23: error: SDL_mixer.h: No such file or
directory

Any suggestions? Thanks in advance.
