 > I’m really not sure if it would be a good idea to change the xcode
 version in my systems … after years. I’m sure this would open doors to
 other problems. But – isn’t it possible to let the build process use a
 specific compiler or sdk or whatever?

 Agreed. I've been running 8.2.1 pretty much since its release. It
 shouldn't be necessary to go backwards given the earlier SDK is available
 and installed (and works happily for a bunch of other ports, including
 earlier versions of this one).

 Given Evan Miller's earlier comment about the introduction of the symbol
 in the 10.13 SDK, going back to 10.11 SDK won't address, surely, unless
 the port's code base has an issue whereby it expects the symbol in the
 10.12 SDK, instead of 10.13, but not in 10.11. Is it then an upstream fix,
 or can the 10.11 SDK be forced?
