Comment (by ryandesign):

 `configure.cxx_stdlib libstdc++` means the port uses
 /usr/lib/libstdc++.6.dylib, which is not the case here.
 `configure.cxx_stdlib macports-libstdc++` means the port uses
 /opt/local/lib/libgcc/libstdc++.6.dylib, which is the case here, but I was
 not expecting each port that compiles with MacPorts g++ to have to do that
 individually. Why should that be necessary? Why can't MacPorts base do it
 automatically when a port is using MacPorts g++?
