try something like this.  When you exec the file you have to supply a 
globals dictionary that contains whatever globals you want to use (like 
import)

     Py_Initialize();

     bp::object main = bp::import("__main__");
     bp::object py_ = main.attr("__dict__");
     bp::exec_file("conf.py", py_, py_);
     int = bp::extract<int>(py_["some_int_is_here"];
