 error-with-boost-python-installed-by-macports-on-mavericks

 I upgraded to maverics and now the macports version of boost-python
 doesn't work.

 I installed ports: gcc48 and boost +python33.

 I tried to compile this program with c++11 or without c++11:

     #include <boost/python.hpp>
     class A {};
     BOOST_PYTHON_MODULE(libblah) {
       boost::python::class_<A>("A");
     }

 I used cmake, but the build commands generated are below along with the
 linker error that I get:

 a.cc.o
     ld: symbol(s) not found for architecture x86_64

 How can I work around this bug without installing boost by myself.  As
 with this [Related question][1], the symbols in the library

     nm  libboost_python-mt.dylib | c++filt | grep
 boost::python::objects::function_object

 are found:

     0000000000013d60 T
 boost::python::objects::function_object(boost::python::objects::py_function
 const&)
     0000000000013d00 T
 boost::python::objects::function_object(boost::python::objects::py_function
 const&, std::__1::pair<boost::python::detail::keyword const*,
 boost::python::detail::keyword const*> const&)

 However, they have std::__1 prefixes, which do not match what is expected
 in the undefined symbols errors.
