Getting SDL working on MacOS X

[Ryan Burton]

I'm new to D, and I'd like to do some SDL programming on Tiger. I 
downloaded the SDL module from http://www.algonet.se/~afb/d/ and tried 
to build the example testbitmap.d, but I unfortunately get an error that 
I have no idea how to get around.

Typing "make testbitmap" gives this:
gdc -O -frelease -c testbitmap.d
gdc -O -frelease -c picture.d
gdc -O -frelease -c sdl/active.d
gdc -O -frelease -c sdl/cdrom.d

Any help would be much appreciated.
