New description:

 Presently these two ports are failing to build for older macOS releases,
 causing a significant amount of wasted time on the buildbots. (Note that
 the port itself builds quickly. Instead, it's the installation of
 dependencies which takes the bulk of the time.)

 However, this might be easily fixable, perhaps with an appropriate
 compiler blacklist.

 Here's one example, for 10.7:

 https://build.macports.org/builders/ports-10.7_x86_64-builder/builds/72714/steps
 /install-port/logs/stdio

 {{{

 cc1plus: error: unrecognized command line option "-std=c++11"cc1plus:
 error: unrecognized command line option "-std=c++11"
 }}}

 But if the blacklist option doesn't work, we should set `known_fail` for
 older releases, and save precious buildbot time.
