Duplicity fails on MacOS because GPG version parsing fails

Interesting, on my Mac Sierra, it says:

ken@dione:~/stealth$ gpg --version
gpg (GnuPG) 2.0.30
libgcrypt 1.7.5

Not sure who rebranded it, but FSF might just be interested to know....

MacGPG2 (https://github.com/GPGTools/MacGPG2) is the name of the Mac-specific GPG version of GPGtools (https://gpgtools.org). GPGtools is broadly used to have a tighter integration of GPG into MacOS.

There seems to be some issues with which installation of gpg one has. The GPGTools version fails, but the some of the other package installations haven't added the extra text.
