Subject: [bug#64387] [PATCH v2 3/6] gnu: arcan: Fix paths handling.
Date: Thu, 10 Aug 2023 22:16:35 +0400

This patch removes the wrapper and the propagated environment variables
(through 'native-search-paths') and instead patches the paths inside the
source code. This fixes path handling, which seems to be broken now. It
also allows us to use 'setuid', which is required for some features, and
lets the app use its internal path handling criteria, which some dependent
apps expect.

* gnu/packages/arcan.scm (arcan): Fix paths handling.
[arguments]: Add 'patch-paths' phase. Remove 'wrap-program' phase.
[native-search-paths]: Remove.
