Comment (by help@…):

 libstdc++ port isn't what I have in mind. I wanted a way for gcc46 to use
 system libstdc++. I tried just now to replace
 /opt/local/include/gcc46/c++/ content with /usr/include/c++/4.2.1/, but
 gcc failed to understand them correctly and exited with some error about
 _is_pod in cpp_type_traits.h. So incompatibility is both ways :( Unless
 you have something more up your sleeve, it basicly means that these gcc
 ports currently do not work reliably and therefore more or less useless.
