How about (untested code, but I have something pretty similar in my code):

template <class T>
boost::shared_ptr<T> New () { return boost::shared_ptr<T> ( new T ); }

template <class T, typename A1>
boost::shared_ptr<T> New ( A1 a1 ) { return boost::shared_ptr<T> ( 
new T ( a1 ) ); }

template <class T, typename A1, typename A2>
boost::shared_ptr<T> New ( A1 a1, A2 a2 ) { return 
boost::shared_ptr<T> ( new T ( a1, a2 ) ); }

and so on.

Then can you just say:
        shared_ptr<int> sp = New<int> ( 5 );
