+From 6e7dd2c763e2cc79db4cd7173921a4e72ce9b95e Mon Sep 17 00:00:00 2001
+From: Elias Probst <mail@eliasprobst.eu>
+Date: Tue, 5 Oct 2021 02:55:18 +0200
+Subject: [PATCH] Don't use configurable POV-ray path.
+
+Once the POV-ray path is configurable, it'll be written to the LeoCAD
+profile, which will break upon the next update of POV-ray which will
+have a different Nix store path.
