Description (last modified by larryv (Lawrence Velázquez))

See my question here: http://stackoverflow.com/questions/21302238/link-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:

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, 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.
