Comment (by kencu):

 The build still fails, despite the `cxx11` PortGroup. I'm fairly sure this
 is because the link line does not specify `-stdlib` as it should:
 {{{
 /opt/local/bin/clang++-mp-5.0 -L/opt/local/lib
 -Wl,-headerpad_max_install_names -arch x86_64 -Xarch_x86_64 -mmacosx-
 version-min=10.8 -o scidavis.app/Contents/MacOS/scidavis

 -F/opt/local/Library/Frameworks -framework QtGui -framework QtCore
 -framework QtXml -framework QtOpenGL -framework QtNetwork
 }}}
 This could be fixed by adding the `stdlib=XXX` onto the `configure.cxx` if
 the compiler is `clang`, or by digging in and figuring out why the CXX
 flags are being included in the link line.

 If you want any help with this, I can probably get this fixed for you.
