 > Looks like this upstream bug:

 That domain is now owned by someone else. The new URL for this bug report

 > If this requires C++11, 10.8 and earlier shouldn't be blacklisted;
 rather, the cxx11 1.0 portgroup should be used, which will explain the
 situation to the user.

 Their readme indicates that
 [https://github.com/GothenburgBitFactory/taskwarrior/commit/06521a1b55193883f951388d0ccd3e82d1590f78
 C++14 is required now]. These days, the fix would be to indicate
 `compiler.cxx_standard 2014`. We have successful builds on 10.6 (where we
 use a newer MacPorts clang that defaults to a newer C++ standard) and on
 10.13 and up, and failures on 10.7-10.12, making it likely that just
 adding that line will fix the problem.
