There's a much easier fix, just define

template<typename T> inline bool operator!=(shared_ptr<T> const & a,
shared_ptr<T> const & b)
{
    return a.get() != b.get();
}

or, in your case,

template <class Iterator, class Policies, class Value,
    class Reference, class Pointer,
    class Category, class Distance>
inline bool
operator!=(
    const
iterator_adaptor<Iterator,Policies,Value,Reference,Pointer,Category,Distance
>& x,
    const
iterator_adaptor<Iterator,Policies,Value,Reference,Pointer,Category,Distance
>& y);

Partial ordering takes care of the rest.
