I have this compile error:
I did this:
std::for_each(map.begin(), map.end(),
    bind( &BlockList::sortY, this,
*bind(&MyMap::value_type::second,
 _1)));
Works for me, boost 1.33 VC7.1:

   class A{};
   typedef std::map<int, A*> MyMap;

   class BlockList {
   public:
     void sortY(A& a) {}

     void doIt() {
       using boost::lambda::_1;
       using boost::lambda::bind;

       MyMap map;
       std::for_each(map.begin(), map.end(),
         bind( &BlockList::sortY, this,
         *bind(&MyMap::value_type::second,
         _1)));
     }
   };
