Thanks Peter, but it does not. Error message 

bind_test.cpp: In function 'int main()':
bind_test.cpp:33: error: no matching function for call to 'bind(<unknown type>, const boost::lambda::lambda_functor<boost::lambda::placeholder<1> >&, const boost::lambda::lambda_functor<boost::lambda::placeholder<2> >&, int)' 

This also dooms my theory of why this doesn't work since the explicit instantiation of the  accumulate template should provide the necessary information.

    bind( std::accumulate< std::vector<int>::iterator, int >, _1, _2, 0 ) 

[Nat] Umm, parentheses() after the std::accumulate template params?
