Rust is not optional. ERPLibre's poetry.lock requires cryptography 46.0.5 with
optional = false, plus jiter, orjson, pydantic-core and rpds-py -- all of which
build Rust from source where no wheel exists, and none exists for s390x. Without
Rust, `pip install cryptography` fails and ERPLibre does not start.
The bootstrap cycle is not the obstacle it looks like: rust-1.90.0 ships an
official s390x-unknown-linux-gnu tarball, verified with HTTP 200, and the host
already carries rustc 1.85.1. What costs is llvm and clang.
Measured before choosing, the way glib2 and iproute2 were: beyond what this port
already has, llvm and clang want libedit, python-psutil, python-sphinx and
python-myst-parser. The last two are documentation only, and behind them sit
docutils, babel, pygments, snowballstemmer, imagesize, alabaster, the
sphinxcontrib family, markdown-it-py and mdit-py-plugins -- some fifteen packages
to render HTML for a compiler whose manual nothing here reads.
-DLLVM_ENABLE_SPHINX=OFF removes all of it.
Their package() ends on `rm -r .../html/{_sources,.buildinfo}`, which Sphinx
creates. Seventeenth appearance of that shape, and the FIRST found before the
build rather than after -- the procedure written in jsoncpp's hook, applied
forwards.
python-psutil is a stage-2 package: built on the host it shipped 41 dist-packages
paths, and the ARTEFACT check caught it.

Rust n'est pas optionnel. Le poetry.lock d'ERPLibre exige cryptography 46.0.5 en
optional = false, plus jiter, orjson, pydantic-core et rpds-py, qui tous
compilent du Rust depuis les sources là où aucune roue n'existe — et il n'en
existe pas pour s390x. Sans Rust, `pip install cryptography` échoue et ERPLibre ne
démarre pas.
Le cycle d'amorçage n'est pas l'obstacle qu'il paraît : rust-1.90.0 publie une
archive officielle s390x-unknown-linux-gnu, vérifiée en HTTP 200, et l'hôte porte
déjà rustc 1.85.1. Ce qui coûte, c'est llvm et clang.
Mesuré avant de choisir, comme glib2 et iproute2 : au-delà de ce que ce portage a
déjà, llvm et clang veulent libedit, python-psutil, python-sphinx et
python-myst-parser. Les deux derniers ne servent qu'à la documentation, et
derrière eux viennent docutils, babel, pygments, snowballstemmer, imagesize,
alabaster, la famille sphinxcontrib, markdown-it-py et mdit-py-plugins — une
quinzaine de paquets pour produire du HTML sur un compilateur dont personne ici ne
lit le manuel. -DLLVM_ENABLE_SPHINX=OFF supprime tout cela.
Leur package() finit sur `rm -r .../html/{_sources,.buildinfo}`, que Sphinx crée.
Dix-septième apparition de cette forme, et la PREMIÈRE trouvée avant la
construction plutôt qu'après — la procédure inscrite dans le hook de jsoncpp,
appliquée à l'endroit.
python-psutil est un paquet d'étage 2 : bâti sur l'hôte, il livrait 41 chemins
dist-packages, et le test ARTEFACT l'a attrapé.
