 Since `+openssl` was removed from 10.1, I wanted to install 10.2. It
 almost finished, but failed at the end.

 I have `clang-5.0` as my default compiler (Lion). And it said:
 {{{

 }}}

 Same on `clang-{6,7}.0`

 `clang-8.0`, which I started with when `clang-5.0` faild, reported:
 `error: expected unqualified-id` - and stopped halfway through.

 I used:

 {{{
 sudo port install mariadb-10.2 +openssl configure.compiler=macports-
 clang-8.0
 }}}

 …and worked my way down to 6.
