We already had a long discussion about QStandardPaths, including /usr/local/share
and environment variables, and we have resolved to avoid both, except where env vars
are used in testing and you run apps from the command-line.  It is MacPorts' standard
policy never to install anything in /usr or /usr/local, see:
    https://trac.macports.org/wiki/FAQ#defaultprefix

The full discussion about QStandardPaths started here:
