What compiler are you using?  The following
compiles for me with msvc 9.0, gcc 3.4.4 and gcc 4.3.0

#include <boost/function.hpp>
#include <boost/bind.hpp>
#include <functional>
#include <iostream>

struct X {
  int foo(int i) { return ++i; }
  template<class T> void foo( T& t );
};

int main()
{
  boost::function<int(int)> f;
  X x;
  f = boost::bind(static_cast<int(X::*)(int)>(&X::foo), &x, _1);
  std::cout << f(5) << std::endl;
}
