I agree with Ryan here. But then again the port depends on poppler
which would probably be built with libstdc++ by default unless the
whole MacPorts is configured to use libc++. I'm not sure what strategy
could be used in these cases.

I tried to build the port on a libstdc++-based system and the
compilation failed with the following error:

/opt/local/bin/clang++-mp-3.4  -pipe -Os -arch x86_64 -stdlib=libc++
-std=c++11  -L/opt/local/lib -Wl,-headerpad_max_install_names -arch
