Seems to me that you need to refer to the type of the member variable, 
not the actual instance, so:

class Test
{
public:
     typedef boost::optional<boost::variant<int, std::string>> Value;
     Value m_value;
};

auto b2 = boost::lambda::bind(Test::Value::get_value_or,
boost::lambda::_1, "empty");

WBR,
