libSDL_ttf

I think I have messed up something in my makefile. If I try to access
any routine from SDL_ttf, i get the error : undefined reference to
TTF_Init (for example).
I include <SDL/SDL_ttf.h> and that is done without any error. And I have
set up the following line to my makefile:

-lpthread -L/usr/local/lib/ -lSDL -lttf

The dynamic-librarys are both in /usr/local/lib/ the headers are in
/usr/local/include/SDL/

I am using KDevelop as IDE. The versions are :
KDevelop: 1.2,
SDL: 1.1.so.0.5.0,
SDL_ttf: 1.2.so.0

Has anyone an idea, what I did wrong ? Maybe I compiled the wrong
versions ?

Greetings,

Sascha

-lpthread -L/usr/local/lib/ -lSDL -lttf

You forgot -lSDL_ttf
