Build problem: Bazel trying to download zlib from bad URL

[philtomson]

I managed to get the make install to work with OCaml 4.08.1. (there were issues with mismatching checksums for rules_cc and rules_proto in the WORKSPACE file - apparently the checksums have changed, see this article: https://github.blog/changelog/2023-01-30-git-archive-checksums-may-change/ - I managed to get it working by changing the expected checksums)

However, make build fails because bazel is trying to fetch zlib from a bad URL:

INFO: Repository zlib instantiated at:
/home/phil/build/bolt/WORKSPACE:38:25: in

I've not been able to figure out where that zlib URL is defined so I can change it.

I am also facing the exact same issue because of the broken URL and it is probably coming from WORKSPACE file. However, could not resolved it yet.
