audacity @2.2.0: error: unknown type name 'unique_ptr'

[ryandesign (Ryan Carsten Schmidt)]

audacity 2.2.0 fails to build on Mountain Lion and earlier with:

./MemoryX.h:398:27: error: unknown type name 'unique_ptr'
      using scalar_case = unique_ptr<X>;
                          ^

I expect this needs the cxx11 1.1 portgroup, but haven't tested it.

AFAICT this is because of an updated dependency, probably wxWidgets. If that is indeed the case, the cxx11 PG should be included by the wxWidgets PG.

This issue was probably resolved as of [3051359ae8/macports-ports] when the cxx11 1.1 portgroup was added to the port.

Probably, audacity has also been updated so I suppose that this ticket can be closed
