Comment (by jeremyhu@…):

 Small correction... `-undefined dynamic_lookup`, not `-undefined dynamic`

 Kicked off my Leopard VM, and indeed we see the compiler warnings about
 the implicit declaration:
 {{{
 pangocoretext-shape.c:153:11: warning: implicit declaration of function
 'CFStringIsSurrogateHighCharacter' is invalid in C99 [-Wimplicit-function-
 declaration]
       if (CFStringIsSurrogateHighCharacter (CFStringGetCharacterAtIndex
 (cstr, i)) &&
           ^
 pangocoretext-shape.c:155:11: warning: implicit declaration of function
 'CFStringIsSurrogateLowCharacter' is invalid in C99 [-Wimplicit-function-
 declaration]
           CFStringIsSurrogateLowCharacter (CFStringGetCharacterAtIndex
 (cstr, i + 1)))
           ^
 pangocoretext-shape.c:199:16: warning: implicit declaration of function
 'CFStringGetLongCharacterForSurrogatePair' is invalid in C99 [-Wimplicit-
 function-declaration]
         return CFStringGetLongCharacterForSurrogatePair (ch, ch2);
                ^
 }}}

 and the subsequent usage of -undefined dynamic_lookup (via -Wl,-undefined
 -Wl,dynamic_lookup):
