If anyone wants to test this with Dianara-dev, now they just need to add DEFINES+=MEDIAGOBLIN in the 'qmake' step, when building from source.

So, instead of what in my instructions is "qmake ..", you should run:

qmake DEFINES+=MEDIAGOBLIN ..

Should work fine against any GMG server running up to date git master.

Anyone already using Dianara can avoid messing up their current configuration by running "Dianara --config somenameforthegmgaccount".
