BPL - function pointers / callbacks?

Hello,

I'm looking into wrapping the Fast Light Toolkit with
BPL. Some member functions take pointers to static
functions which will be used as callbacks.

The callback function signature is:   
        void callback( Fl_Widget *, void *)

This is registered with:
  typedef void (Fl_Callback)(Fl_Widget *, void *);
  void Fl_Widget::callback(Fl_Callback *c, void *p);

The error this results in is:
/home/kpd/src/boost-1.20.2/boost/python/caller.hpp:653:
no matching function for call to `from_python
(PyObject *&, boost::python::type<void (*)(Fl_Widget
*, void *)>)'
/home/kpd/src/boost-1.20.2/boost/python/conversions.hpp:80:
candidates are: long int from_python(PyObject *,
boost::python::type<long int>)
.
.
.

So, do I need to add the widget type to boost, that
doesn't sound right.  

Do I need to change the interface to a Py_Object?  

Searching the archives did not reveal anything.  
Would someone be kind enough to post an example of
registering a callback function?

Thanks for your help!
