You should not export export "SmartPtr" class as is. You can "teach"
Boost.Python to understand that an object is the instance of SmartPtr
class and it will handle for you and your users "operator*" and
"operator->".

The following example (
http://language-binding.net/pyplusplus/troubleshooting_guide/smart_ptrs/smart_ptrs.html
) should help you. Also, in the past there were a lot of discussions
on this subject, so using Google will definitely help.
