Don't use the devel/libc++ port, it is pretty much outdated.  It was
only created as a stopgap measure, and should really be deleted now that
FreeBSD 9.x is EOL.

In any case, at the moment, no released version of FreeBSD has a version
of libc++ new enough to support std::variant.  We are working on
importing clang and libc++ 4.0.0, in the projects/clang400-import
branch.  This version has std::variant support.

I expect this branch to be merged to FreeBSD 12 in a few weeks, then
merged to FreeBSD 11 at least a month later.
