Comment (by kencu):

 It's another joy of building everything with `clang-9.0` on older systems,
 living out here on the fringes of the solar system with a shiny new
 compiler that pretty much nobody is using much yet :>

 It builds with `clang-5.0` easily enough. I tried setting the c++ standard
 to c++11 with
 {{{
 configure.cxxflags-append -std=c++11
 }}}
 but it didn't get plumbed everywhere, and failed.

 So I tried appending it onto the compiler spec
 {{{
 configure.cxx-append -std=c++11
 }}}
 but that failed in configure.

 So I did this, and moved on:
 {{{
 sudo port -v install mariadb configure.compiler=macports-clang-5.0
 }}}

 {{{
 $ port -v installed mariadb
 The following ports are currently installed:
   mariadb @5.5.65_0 platform='darwin 10' archs='x86_64'
 date='2019-08-17T13:19:42-0700'
   mariadb @5.5.66_0 (active) platform='darwin 10' archs='x86_64'
 date='2019-11-12T07:37:36-0800'
 }}}
