Comment (by RJVB):

 Replying to [ticket:56097 mojca]:

 > To me this looks like a completely missing block with
 `-D_GLIBCXX_USE_CXX11_ABI=0 -stdlib=macports-libstdc++ -arch x86_64 -fPIC
 -Wall` in compiler call.

 You mean in the compile command for PluginAdapter.cpp? In my builds that
 command does include the expected CXXFLAGS.

 Do I understand correctly that the legacy builders try to build the port
 without C++11? That should probably work for libvamp (if it's really that
 old), but I'm not sure it will for the rest of the port. Building with a
 recent GCC might work out better, but how can we achieve and test that?
