library not found for -lc++

I'm trying to build an Xcode 3.2 project (previously built on 10.6.8) on Xcode 7.2, (on 10.10). I've installed the 10.6.8 SDK correctly (I think). I'm getting the linker error: "ld: library not found for -lc++" what does this mean?

Just in case anyone has the same issue, I solved this by asking elsewhere(!) and following advice to download and run the script from:
