I downloaded scapy manually since for some reason, after using macports, it
wouldn't find the package at all.

I am also trying to install libdnet manually as mentioned above, so after
./configure && make I go into the python directory & do a  python setup.py
install, which generates a bunch of warnings & the following two errors:

/dnet.c:2729:4: error: assignment to cast is illegal, lvalue casts are not
supported
  ((PyObject*)__pyx_v_next) = Py_None; Py_INCREF(((PyObject*)__pyx_v_next));
  ~^~~~~~~~~~~~~~~~~~~~~~~~ ~
./dnet.c:2741:6: error: assignment to cast is illegal, lvalue casts are not
supported
    ((PyObject *)__pyx_v_next) = __pyx_3;
    ~^~~~~~~~~~~~~~~~~~~~~~~~~ ~


Thanks again for any help.  Need to get all this working for this
mini-project and also because I am starting a SANS class that leverages
scapy quite a bit...
