That is strange, I remember fixing that... I'll check everything once more.
Until then, you may try this workaround:

 int main (int, char **) {
   vector<int> values;
   vector<string> ret;

   typedef std::string(*f2)(const int&);
   f2 p2 = &boost::lexical_cast<std::string, int>;

   std::transform(values.begin(), values.end(), ret.begin(), p2);
 }
