Swig Python C on Mac

I tried the Swig tutorial without much success. I was getting problems ranging from ugly link time messages:

Undefined symbols for architecture x86_64:
  "_PyArg_ParseTuple", referenced from:
      __wrap_fact in example_wrap.o
      __wrap_my_mod in example_wrap.o
      __wrap_get_time in example_wrap.o
  "_PyArg_UnpackTuple", referenced from:
      _SwigPyObject_own in example_wrap.o

to segmentation faults.

This is what finally worked (for me):

swig -python example.i
gcc -c example.c example_wrap.c -I/usr/local/Cellar/python3/3.5.1/Frameworks/Python.framework/Versions/3.5/include/python3.5m
gcc -dynamiclib *.o -o _example.so /usr/local/Cellar/python3/3.5.1/Frameworks/Python.framework/Versions/3.5/lib/libpython3.5m.dylib

Good luck!
