[PyKDE] Simple sip program

I was trying out a simple sip program before progressing to bigger and
better things. However I can't seem to make it work. Here is the sip
%Module hello

class world
#include "hello.h"
	const char* get() const;

const char* sayit();

And here is the C++ implementation:

class world
	world() {}
	~world() {}
	const char* get() const { return "hi"; }

const char* sayit()
	return "sayit";

The module compiles fine but I get an error when I try to create a class
instance of world:

ufo:/home/ggreen/code/bpl > python
Python 2.0 (#8, Jan 24 2001, 13:10:20) [C] on irix646-n32
Type "copyright", "credits" or "license" for more information.
>>> import hello
>>> h = hello.world()
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "hello.py", line 11, in __init__
TypeError: Invalid argument types to world()

BTW, PyQt works fine so I don't think it is a build problem. I also
attached my Makefile.
