Actually, me the dummy, provided for you all what MacPorts has, not what I have :-)

This is what I have installed via MacPorts:
port installed | grep sdl
  libsdl2 @2.24.2_0
  libsdl2 @2.26.1_0
  libsdl2 @2.26.2_0
  libsdl2 @2.26.3_0
  libsdl2 @2.26.4_0
  libsdl2 @2.26.5_0
  libsdl2 @2.28.0_0 (active)

sdl2-config --cflags
-I/opt/local/include/SDL2 -D_THREAD_SAFE

sdl2-config --libs
-L/opt/local/lib -lSDL2

Well, that would probably explain the problem :-)
