initenv.sh fails while building wheels for chatmaild and crypt-r

[trollkotze]

• Server OS (Operating System) - preferably Debian 12: Debian 12
• On which OS you run cmdeploy: not running cmdeploy yet, just scripts/initenv.sh, but of course I'd still be on Debian 12 if I got that far

Expected behavior

What did you try to achieve?
I followed the instructions in the README under "Getting Started" to set up a chatmail server.
Under step 2, setting up the Python virtuelenv, I tried to run scripts/initenv.sh

Actual behavior

What happened instead?
There was some error building a wheel for crypt-r.

Steps to reproduce the problem:

 git clone https://github.com/chatmail/relay
 cd relay
 scripts/initenv.sh

Okay, I just needed to install python3.11-dev.
Maybe this should be added to the REDAME:

apt install python3.11-dev python3.11-venv

[adonm]

Interestingly, I've been using uv (installed via homebrew) instead of debian packaged python and that seems to pull in crypt-r without building

Example here https://codeberg.org/adonm/adonm-dev-iac/src/branch/main/pyproject.toml is sufficient to have uv sync and uv run scripts/cmdeploy ... work - I could do a pull request with config for uv to work directly (as an alternate to having to initenv first) if anyone interested?
