Comment(by kashif):

 Yes so that's what I tried initially, a one line change:

 -AC_CHECK_LIB([json], [json_object_get], [HAVE_JSON=yes], [], [])
 +AC_SEARCH_LIBS([json_object_get], [json-c json], [HAVE_JSON=yes], [], [])

 And it finds the newer json-c, but when compiling I get a linker error:

 $ make
 ....
 st_2d.o gserialized_gist_nd.o gserialized_estimate.o geography_inout.o
 geography_btree.o geography_measurement.o
 geography_measurement_trees.o geometry_inout.o

 clang: error: linker command failed with exit code 1 (use -v to see

 make: *** [all] Error 1

 and it seems that the -Wl,-dead_strip_dylibs  flag is striping out the
 libjson-c which is linked into the the older libjson shared lib:

 $ otool -L libjson.0.dylib
 libjson.0.dylib:
     /usr/local/lib/libjson.0.dylib (compatibility version 2.0.0, current
 version 2.0.0)
     /usr/local/lib/libjson-c.2.dylib (compatibility version 3.0.0, current
 version 3.0.0)
     /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current
 version 169.3.0)

 I have an issue about it on github:
 https://github.com/json-c/json-c/issues/79

 Hope this helps.
