Comment (by Veence):

 Ok, I’ve attached a new Portfile.

 This one lets you choose between QT4+Py2.7 or QT5+Py3.6. You cannot have
 QT5+Py2.7, this is forbidden by QGIS. I don't think that QT4+Py3.6 is
 allowed either, that would not make sense anyway.

 QT5 is now the DEFAULT choice.

 QT4+py2.7 is untested so far. Please by all means give it a crack (+qt4
 option).

 Grass 6 is obsolete. +grass hooks to Grass 7. Please install it (currently
 v 7.2).

 That’s all folks. Please let me know. If it works, I shall commit it.

 Thanks for you patience all those months. Much appreciated. ❤️
