---------------------+----------------------
 Compilation fails for 10.7 thru 10.11, with the following. Based on local
 testing, use of pg `legacysupport`/`macports-libcxx` is enough to take
 care of it, though:

 {{{

 }}}

 With that fix in place, the final link fails, due to use of `--exclude-
 libs=ALL`. Presumably that is also easily-fixable.
