Thanks Glynn.
Here is the relevant section from config.log:

------------------------------------------------------------------------------------------------
configure:12938: checking for cairo_create
configure:12964: gcc -o conftest -g -O2   -arch i386    -I/usr/include
   -arch i386   -L/usr/lib conftest.c  -L/sw/lib -
lcairo   -L/sw/lib -lfontconfig  1>&5
ld: library not found for -lfontconfig
collect2: ld returned 1 exit status
configure: failed program was:
#line 12941 "configure"
#include "confdefs.h"
/* System header to define __stub macros and hopefully few prototypes,
    which can conflict with char cairo_create(); below.  */
#include <assert.h>
/* Override any gcc2 internal prototype to avoid an error.  */
/* We use char because int might match the return type of a gcc2
    builtin and then its argument prototype would still apply.  */
char cairo_create();

int main() {

/* The GNU C library defines this for functions which it implements
    to always fail with ENOSYS.  Some functions are actually named
    something starting with __ and the normal name is an alias.  */
#if defined (__stub_cairo_create) || defined (__stub___cairo_create)
choke me
#else
cairo_create();
#endif

; return 0; }
------------------------------------------------------------------------------------------------

... updated to latest SVN, and now configure outputs a more useful
error message:

configure: error: *** Unable to locate cairo_create.

... removing '--with-cairo-ldflags=-lfontconfig' allows configure to
complete, and running make results in:

gcc -I/usr/include -g -O2   -arch i386 -fno-common -I/usr/include
-I/Users/dylan/src/grass_trunk/dist.i386-apple-darwin9.8.0/include
-I/Users/dylan/src/grass_trunk/dist.i386-apple-darwin9.8.0/include
-D_FILE_OFFSET_BITS=64 -I../driver -I/usr/X11/include/libpng12
-I/usr/X11/include -I/usr/X11/include/freetype2 -I/sw/include
-I/sw/include/cairo   -I/sw/include/cairo  -I/usr/X11/include
-DUSE_X11=1 -DPACKAGE=\""grasslibs"\"

OBJ.i386-apple-darwin9.8.0/Graph.o -c Graph.c
Graph.c:19:23: error: cairo-svg.h: No such file or directory

... look like I need to do some more homework.

Thanks,
