However, upstream claim to be targeting 10.8 and 10.9, so I would hope it would work on OSX10.8 as well (to be tested sometime, by someone who has access to a 10.8 machine). Whilst not ideal, I think this is reasonable coverage (given root5 will remain available for all versions).

Well, libc++ (with full C++11 support) is included in 10.8, it’s just not the default. As long as root doesn’t use any other libraries, it should build fine with that, if you instruct it to. But then any other software that wants to use root would have to do that as well.
