`pyside6` requirement confuses OpenBSD

[klsrqm]

OpenBSD manages many python packages via its packages and for security and compatibility reasons does not tend to allow system-wide installation of pip packages.

PySide6 is available via OpenBSD ports as the following packages:
For -stable:

pyside6-6.8.3
pyside6-tools-6.8.3

For -current:

pyside6-6.10.1      Python Qt bindings for Qt 6
pyside6-tools-6.10.1 PySide6 development tools

These versions should satisfy requirements.

PySide6 is installed and is accessible to Python:

$ pkg_info -m | grep pyside
pyside6-6.10.1      Python Qt bindings for Qt 6
pyside6-tools-6.10.1 PySide6 development tools

$ python3
>>> import PySide6
>>> PySide6.__file__
'/usr/local/lib/python3.13/site-packages/PySide6/__init__.py'

However:

$ pipx install typstwriter                                                    
Fatal error from pip prevented installation. Full pip output in file:
    $HOME/.local/pipx/logs/cmd_2025-12-19_09.45.41_pip_errors.log

Log file says:

Additionally, some packages in these conflicts have no matching distributions available for your environment:
    pyside6

The same error happens if I try to install it in a VENV via pip.

WORKAROUND I FOUND:

1. Clone repo
2. Create a venv with system-site-packages:

typstwriter$ python3 -m venv --system-site-packages .venv

3. REMOVE the dependency from pyproject.toml:

diff --git a/pyproject.toml b/pyproject.toml
index 5941b74..3471831 100644
--- a/pyproject.toml
+++ b/pyproject.toml

 "qtpy >= 2.3",

4. Install local version:

(.venv) $ pip install .

Typstwriter runs fine this way.
