I should have scanned the python c++ SIG first.  Also now realize 
that python.boost questions are preferred on that list rather than 
here.

For future newbie reference, solution to above appears to be:

struct Bar
{
     void func( const std::string& s );
     void func( int i );
};

BOOST_PYTHON_MEMBER_FUNCTION_OVERLOADS( Bar_func_overloads, 
Bar::func, 1, 1 )

BOOST_PYTHON_MODULE( Foo )
{
class_<Bar>( "Bar" )
.def("func",(void(Bar::*)(const std::string&))0,Bar_func_overloads)
.def("func",(void(Bar::*)(int))0,Bar_func_overloads)
;
}
