One trivial way to "fix" it is to force it to build with clang-7.0: 

$ port -v installed modglue
The following ports are currently installed:
  modglue @1.19_0 (active) platform='darwin 17' archs='x86_64' date='2018-09-13T23:46:38-0700'

clang-7.0 defaults to c++17 I believe, and so takes all the c++11 needs in stride without any changes in the portfile or the port. To fix it correctly I believe getting -std=c++11 onto the build and link lines would do the trick. Should also add the -stdlib=${configure.cxx_stdlib} while we're at it, along with all the other CXX flags.

This sounds like a two-day project for me, or two minutes for Ryan :>

The clang in Xcode 10: 

$ /usr/bin/clang --version
Apple LLVM version 10.0.0 (clang-1000.11.45.2)
Target: x86_64-apple-darwin17.7.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

does not build this, however, so I guess it still is defaulting to the old c++ standard.
