Looks like there is an issue with latest xcode as per stackoverflow
./boost/container_hash/hash.hpp:132:33: error: no template named 'unary_function' in namespace 'std'; did you mean '__unary_function'?
struct hash_base : std::unary_function<T, std::size_t> {};
~~~~~^~~~~~~~~~~~~~
__unary_function
This is caused by https://developer.apple.com/documentation/xcode-release-notes/xcode-15-release-notes#Deprecations and we are use boost 1.78 (1.81 and after should be fine).
Specifically, in order to compile, we need to add -D_LIBCPP_ENABLE_CXX17_REMOVED_UNARY_BINARY_FUNCTION compiler flag.
For main branch, this is fixed by #11017
