Expected behavior

Lodestar should build on macOS 15.5. It was not reproducing on some other Mac M2s with the same configuration, this one was unique to the reporter's environment.

Steps to reproduce

No response

Additional context

User reports using:

MacOs 15.5
Node v22.14.0

After consulting with AI, this error could be due to our outdated blst submodule of c-kzg and we may need to update c-kzg to resolve. For AI context, see: https://www.perplexity.ai/search/when-trying-to-build-c-kzg-for-U.ZLj5WMRs67AUNFSJzeEA
