[bug#53878] [PATCH v2 02/15] gnu: chez-scheme: Use "lib/chez-scheme" for


From: Philip McGrath
Subject: [bug#53878] [PATCH v2 02/15] gnu: chez-scheme: Use "lib/chez-scheme" for search path.
Date: Thu, 17 Feb 2022 15:50:35 -0500

There does not seem to be any widely accepted standard path to use for
"CHEZSCHEMELIBDIRS". Using a path without a version number in it avoids
having to compute the actual path everywhere, which would be especially
unpleasant when support is added for the Racket variant of Chez Scheme,
which always has a different version number than upstream.

* gnu/packages/chez-and-racket-bootstrap.scm
(chez-scheme)[native-search-paths]: Change to use "lib/chez-scheme"
instead of "lib/csvX.Y.Z-site" for "CHEZSCHEMELIBDIRS".
* gnu/packages/chez.scm (chez-srfi, chez-web, chez-sockets,
chez-matchable, chez-irregex, chez-fmt, chez-mit, chez-scmutils): Update
accordingly. Also, remove input labels and use G-expressions.
