 Replying to [comment:9 ryandesign@…]:
 > Therefore, compile your own code using the system's libstdc++ too; don't
 use FSF GCC's libstdc++.

 I'd be happy to do that, but as of today, this is not possible on Mac
 Ports, because the system's lib for C++ is libstdc++, but if I don't pass
 -stdlib=c++, then c++ (the native C++ compiler) does not support C++11.
 So:

 - GCC is not an option, as it does not use the system's library:
 {{{
 $ cat /tmp/foo.cc
 #include <memory>
 #include <boost/filesystem.hpp>
 #include <iostream>

 int main()
 {
   auto p = std::make_shared<boost::filesystem::path>("abc");
   std::cerr << p->is_absolute() << std::endl;
   std::cerr << absolute(*p) << std::endl;
 }
 $ g++-mp-4.8 -std=c++11 -ggdb -Wall foo.cc -lboost_filesystem-mt
 -lboost_system-mt -L/opt/local/lib -I/opt/local/include
 $ ./a.out
 a.out(82426) malloc: *** error for object 0x108bc4570: pointer being freed
 was not allocated
 *** set a breakpoint in malloc_error_break to debug
 zsh: abort      ./a.out
 }}}

 - clang is not an option, where from Xcode or from MacPorts, because its
 system's library does not support C++11
 {{{
 $ c++ -std=c++11 -ggdb -Wall foo.cc -lboost_filesystem-mt -lboost_system-
 mt -L/opt/local/lib -I/opt/local/include
 foo.cc:7:17: error: no member named 'make_shared' in namespace 'std'
   auto p = std::make_shared<boost::filesystem::path>("abc");
            ~~~~~^
 foo.cc:7:52: error: expected '(' for function-style cast or type
 construction
   auto p = std::make_shared<boost::filesystem::path>("abc");
                             ~~~~~~~~~~~~~~~~~~~~~~~^
 2 errors generated.
 $ c++ -std=c++11 -stdlib=libc++ -ggdb -Wall foo.cc -lboost_filesystem-mt
 -lboost_system-mt -L/opt/local/lib -I/opt/local/include
 $ ./a.out
 zsh: segmentation fault  ./a.out
 }}}

 So, unless I missed an option, one cannot use Boost and C++11 on MacPorts
 today.
