Comment (by kencu):

 The issue here is that `protobuf3-cpp` now REQUIRES all software using it
 to be built with at least `-std=c++11`. Only the most recent `clang`
 versions default to that, so that flag will need to be added to all
 builds.

 In addition to the `PG cxx11 1.1`, you need
 {{{
 configure.cxxflags-append -std=c++11
 }}}

 and then it builds.
