9.461 Note: This error originates from the build backend, and is likely not a problem with poetry but with xmlsec (1.3.13) not supporting PEP 517 builds. You can verify this by running 'pip wheel --use-pep517 "xmlsec (==1.3.13)"'.

Ah i managed to install it on linux ( inside docker on python:3.11.5-slim-bookworm image )

apt install build-essential pkg-config libxml2-dev libxmlsec1-dev libxmlsec1-openssl libpython3.11-dev

it then installs python3-saml via poetry
