gdc -o main main.d -arch i386 -fversion=Tango -fversion=Posix \
     -isysroot /Developer/SDKs/MacOSX10.4u.sdk -lgtango -lz -lssl

As a one-time setup thing (and for convenience), you need to set up
symbolic links for libgphobos.a and libgtango.a to the SDK dir too:

sudo ln -s /usr/lib/libgphobos.a /Developer/SDKs/MacOSX10.4u.sdk/usr/lib
sudo ln -s /usr/lib/libgtango.a /Developer/SDKs/MacOSX10.4u.sdk/usr/lib

PS.
You can also build universal binaries, by using "-arch ppc -arch i386"
