cause reth-zstd-compressors - zstd - zstd-safe - zstd-sys included in dependency tree.
This cause zkvm toolchain fail to build, since cc is not available.
grep zstd-sys Cargo.lockto confirmzstd-sysis not in the dependency tree.- run
cargo openvm buildto see if it works without err. (if you don't havecargo-openvm, see https://book.openvm.dev/getting-started/install.html)
