It seems more complicated that I thought. After fixing the includes,
to use the KingChaos Frameworks, recompiling results in:

In file included from Graph.c:19:
/Library/Frameworks/cairo.framework/unix/include/cairo/cairo-svg.h:79:3:
error: #error Cairo was not compiled with support for the svg backend
make: *** [OBJ.i386-apple-darwin9.8.0/Graph.o] Error 1

Can SVG be disabled somehow?
