Try:

#include <list>
#include <algorithm>
#include <boost/lambda/bind.hpp>
#include <boost/lambda/lambda.hpp> //added

int main()
{
    using namespace boost::lambda;

    std::list<std::list<int> > l;
    bool some_are_empty = false;

    std::for_each(l.begin(), l.end(), var(some_are_empty) = 
bind(&std::list<int>::empty, _1) || var(some_are_empty));
                                    ^^^^              ^
    return 0;
}
