Hi, For me, I’m afraid, I think this means ROOT6 can only be properly supported on 10.8 or newer. As its only these OS versions that have c++11 support. If upstream have decided ROOT from version 6 onwards requires c++11 support, I am not going to second guess them.
I previously had variants in the ROOT port that allowed users to build the C++ sources with gcc, but this lead to all the well know issues and was removed. I will not be adding it back. Unofficially, you might have luck on 10.7 with > sudo port install root6 configure.compiler=macports-gcc-4.8 but given the issues, it will have to stay unofficial...
