py-pydantic V2



Hi all,

I realize pkgsrc is only providing V1 of py-pydantic. V2 was rewritten in Rust, and this version is not yet available as a pkgsrc package. I tried to install it directly with pip, but the installation process fails with a rust compile error. Using Python 3.11, rust 1.73.0, latest pkgsrc-2023Q4 and NetBSD-10.0-RC3.

Actual goal is to get the most recent openai Python package installed on my NetBSD machine. I have an old 0.28 version from last summer successfully installed, but the upgrade to the current version now fails.

Anybody has an advice for me how to get openai-1.10.0 / pydantic-core-2.16.1 installed? Thank you so much for a hint!

This is the error I get:

% sudo pip3.11 install pydantic-core

note: This error originates from a subprocess, and is likely not a problem with pip.
