I’ve known and use (almost solely for panos) hugin for some years. And yes I’ve checked that thread and actually that’s the one which led me to paperdigit’s expanded tuto based on yours; beginning of kittens thread, so a bit late thank you 
For now I’ll change beds like the good whore I am from LR’s enfuse to hdrmerge, to hugin, to median stack, always preferring the mucho-macho pals that eat raw, back to pfs aparently thick paste (trying to understand WTF pfshdrcalibrate is so sad) and then dance for a bit with amazonic hydrogen akira sub_hdrgen and a pill boost 4 all the lonely grandmas, to go back to fdr tools, hello pictureduck, by means of dcraw, give the watching brother (gui) a wink and zero noise another try, be a snob about luminance HDR and tease the imagefuser GUI just for fun. The less open softwera won’t be publicise.
Concerning the pfbatch command, I forgot you are under OSX… it is not included in the bundle at the moment, but it should be relatively easy to add it.
Looking forward — cataracts. A good weekend for y’all
