Comment (by ryandesign):

 As I said, a revbump alone is insufficient. You're building with gcc6,
 which uses libgfortran.3.dylib. That's no longer part of libgcc; it's now
 part of libgcc6. So you either need to build with gcc7, which uses
 libgfortran.4.dylib which is part of libgcc, or you need to change the
 libgcc dependency to libgcc6.
