Nixpkgs commit 451c6321 upgraded setuptools from version 65.0.3 to
version 67.4.0. This upgrade introduced a breaking change in
setuptools [1] which causes the Sapling package's build to fail:
setuptools.extern.packaging.version.InvalidVersion: Invalid version: '0.2.20230124-180750-hf8cd450a'
This is an upstream issue [2]. For now, work around this issue in
Nixpkgs by truncating Sapling's version number.
Before 451c6321:
$ nix-env -q sapling
sapling-0.2.20230228-144002-h9440b05e
$ sl --version
Sapling 0.2.20230228-144002-h9440b05e
After this patch:
$ nix-env -q sapling
sapling-0.2.20230228-144002-h9440b05e
$ sl --version
Sapling 0.2.20230228
