+Subject: [PATCH] Remove deprecated use of distutils, fix for Python 3.12+
+
+Remove deprecated use of distutils, fix for Python 3.12+
+
+This switches to using sysconfig from distutils, which is necessary for
+Python 3.12+ since distutils is deprecated and has been removed.
+
+It is necessary to specify the install scheme when a prefix other than
+the Python default is used so that changes to the default scheme made by
+distributions (e.g. Debian, Fedora) do not produce an incorrect Python
+installation directory. For example, Debian patches the default scheme
+to prepend the path with '/local', but if a user specifies a prefix of
+'/usr/local', then the path using the default scheme would be
+'/usr/local/local/...' with a duplicated 'local' directory. Specifying
+an unmodified install scheme fixes that.
