SDL, ошибки при «компиляции».

Пробую "скомпилировать" простейший пример (например, из http://www.libsdl.org/cgi/docwiki.cgi/Initializing_SDL ) командой наподобие "gcc -o test sdl_i.c `sdl-config --cflags --libs`"

("sdl-config --cflags --libs" выдаёт
-I/usr/include/SDL -D_GNU_SOURCE=1 -D_REENTRANT
-L/usr/lib -Wl,-rpath,/usr/lib -lSDL -lpthread
) и получаю следующее:

В чём может быть причина?
