[CM] and on osx

[Neuwirth Erich]

I am trying to build snd on my Mac (OSX 10.7.4), but I get the following error

\In file included from snd.h:48,
                 from headers.c:40:
snd-g0.h:15:25: error: cairo/cairo.h: No such file or directory
make: *** [headers.o] Error 1

Can anybody help overcoming this problem?
