Clang's versioning seems not consistent. $ clang --version Apple LLVM version 5.1 (clang-503.0.40) (based on LLVM 3.4svn) Target: x86_64-apple-darwin12.6.0 Thread model: posix Does this mean that I have 3.4 or something around that time of release? What exact port should then I install in order to have a modern compiler as you suggest? llvm-4.0 or clang-4.0? And which configuration in macports.conf? I don't seem to find the right option in the guide, https://guide.macports.org/chunked/internals.configuration-files.html. > 2. properly setting the standard c++ library. I'm now always building from source with libc++. If I change compiler, what are the odds that I run into some other oddities with the installed ports built with the default compiler?
