What version of boost? Can you post a minimal example? It works here:

testbed.cpp:

#include <boost/shared_ptr.hpp>

class X;

boost::shared_ptr<X> create();

int main()
{
    boost::shared_ptr<X> px = create();
}

testbed2.cpp:

#include <boost/shared_ptr.hpp>
#include <iostream>

class X
{
public:

    X()
    {
        std::cout << "X::X()\n";
    }

    ~X()
    {
        std::cout << "~X::X()\n";
    }

private:

    X(X const &);
    X & operator= (X const &);
};

boost::shared_ptr<X> create()
{
    boost::shared_ptr<X> px(new X);
    return px;
}

Output:
