#check_broken_sdks ⇒ String?

This method is part of a private API. This method may only be used in the Homebrew/brew repository. Third parties should avoid using this method if possible, as it may be removed or changed without warning.

The CLT 10.x -> 11.x upgrade process on 10.14 contained a bug which broke the SDKs. Notably, MacOSX10.14.sdk would indirectly symlink to MacOSX10.15.sdk. This diagnostic was introduced to check for this and recommend a full reinstall.

    You have pkgconf installed that was built on macOS #{built_on_version}
             but you are running macOS #{current_version}.

    This can cause issues with packages that depend on system libraries, such as libffi.
    To fix this issue, reinstall pkgconf:
      brew reinstall pkgconf

    For more information, see: https://github.com/Homebrew/brew/issues/16137
    We'd welcome a PR to automatically mitigate this instead of just warning about it.
