Wed Apr 26 06:11:08 UTC 2017

Is this the sort of version cross-reference you're looking for?

>>> Like most ports, the ImageMagick port uses the default compiler for the currently running macOS / Xcode version (i.e. clang on OS X 10.7 and later). The portfile doesn't contain any statements about openmp so I have no idea whether the port supports openmp. My understanding is that support for openmp was added in clang 3.8 if that helps.

They used to tell us what FSF versions of clang those correspond to, but they don't anymore. I don't know what FSF version of clang Apple LLVM 8.1 corresponds to. Jeremy Sequoia probably knows.
