smart_ptr is shared_ptr right?

It doesn't work fork me. I have compile time error saying that:

error C2440: 'initializing' : cannot convert from
'smart_pointers::data *' to 'data_wrapper *'
Cast from base to derived requires dynamic_cast or static_cast

I am using msvc 7.1

I do have solution, I just wanted to attract attention of boost.python

Any way, thanks for help.
