Personnally I define all prototypes possible and it works:
.def("someMethod",
(std::string(someClass::*)(std::string,std::string,std::vector<std::string>))
&someClass::someMethod)
.def("someMethod",
(std::string(someClass::*)(std::string,std::string,std::vector<std::string>,int,int,int))
&someClass::someMethod),
.def("someMethod",
(std::string(someClass::*)(std::string,std::string,std::vector<std::string>,int,int))
&someClass::someMethod),
.def("someMethod",
(std::string(someClass::*)(std::string,std::string,std::vector<std::string>,int))
&someClass::someMethod),
