@sthen thank you for packaging trippy for openbsd.

In #920 I've enabled building for OpenBSD in CI however it fails with:

error: component 'rust-std' for target 'x86_64-unknown-openbsd' is unavailable for download for channel 'stable'

Which Rust version did you build against? OpenBSD is a Tier 3 Rust target so perhaps the stable version lags behind the latest?

Hi, sorry I don't have any idea about the problem you're seeing when you cross-compile. We're currently building with rust 1.75.0 (always native builds for each supported architecture, we don't do any cross-compiles). @semarie is doing a great job of maintaining our rust port and keeping it up to date.

a Tier-3 platform means that rust project doesn't build or test anything for OpenBSD. so there is no component to download on rust servers.

Thanks both. Any recommendations on the best way to enable automated builds in CI and on release?
