It seemed necessary to add a nested bind call.

#include "boost/bind.hpp"
#include "boost/shared_ptr.hpp"

#include <map>

struct WTH
{
  int cut;
};

int main()
{
  int cut;

  typedef std::multimap<int, boost::shared_ptr<WTH> > DataMap;

  std::find_if(myMap.begin(), myMap.end(),
    boost::bind(&WTH::cut,
                boost::bind(&DataMap::value_type::second, _1)) == cut);

  return 0;
}

HTH,

Nate
