Simple enough to symlink the compiler / cctools parts / and ld in the 10.6 SDK to the equivalents in /opt/local. With this, I can force clang-3.9 / libc++ xcode builds on 10.6.8 with a few simple xcode.build.settings, and build lots of things that way. So it’s quite possible, but I don’t know if it’s bakeable into a macports port. Ken
