uv pip fails on BSD: Libc type could not be detected

[lcheylus]

Success to build of uv version 0.2.2 on OpenBSD current/amd64 with Rust version 1.78.0:

$ uv version
uv 0.2.2

$ rustc -vV
rustc 1.78.0 (15adfb9cd 2024-04-28) (built from a source tarball)
binary: rustc
commit-hash: 15adfb9cd5b029268e1470a41391d91859b0a1f8
commit-date: 2024-04-28
host: x86_64-unknown-openbsd
release: 1.78.0
LLVM version: 16.0.6

When I try to exec uv pip list command (or other pip commands), I have the following error:

$ uv pip list
error: Libc type could not be detected

After some analysis, this error seems to come from "Rewrite Python interpreter discovery" #3266. (release in version 0.2.0).

In crates/uv-interpreter/src/platform.rs file, function Libc::from_env, there is no case for BSD OD (freebsd, openbsd, netbsd), only for linux and windows | macos => Error::LibcNotDetected is returned for BSD OS.

I think this function sould return a new value Libc::BSD for BSD OS (specific libc version for this OS type, different from GNU libc).

Could you try with #3825?

[lcheylus]

OK, PR #3825 fixes this issue:

• build of uv v0.2.3 + patch from Ignore libc on other platforms #3825 on OpenBSD current/amd64 with Rust 1.78.0
• uv pip <command> works as attended

$ uv pip list
Package                       Version
----------------------------- ---------
alabaster                     0.7.16
astroid                       3.1.0
attrs                         23.2.0
autopep8                      2.0.4
(...)

Thanks @konstin for your fix.
