Thanks for reporting this, there was quite a stupid mistake in the  
ffi.lisp that prevented PAL from loading the foreign dynamic libraries.
Should be fixed in the CVS by now, alternatively you could change the  
library definitions in the beginning of pal/ffi.lisp to be as follows:

(cffi:define-foreign-library sdl
   (:windows "SDL")
   (:unix (:or "libSDL-1.2.so.0" "libSDL-1.2.so")))

(cffi:define-foreign-library sdl-mixer
   (:windows "SDL_mixer")
   (:unix (:or "libSDL_mixer-1.2.so.0" "libSDL_mixer-1.2.so")))

(cffi:define-foreign-library sdl-image
   (:windows "SDL_image")
   (:unix (:or "libSDL_image-1.2.so.0" "libSDL_image-1.2.so")))

(cffi:define-foreign-library opengl
   (:windows "opengl32.dll")
   (:unix (:or "libGL.so")))

It is possible that you still need to change the lib*.so.n.n versions to  
those matching your installation.
