A new release is available.
Created attachment 287835 [details] ebuild for dispcalGUI 0.7.3.7 Here it is! Sorry for the delay. It didn't need anything, just renaming the old ebuild. I checked for any new or modified dependencies but there weren't any. I tested it on ~amd64 arch and seems ok; all dialogs appear and my colorimeter works.
Thanks Marios. Sorry for the delay. New ebuild is now on portage tree
