https://mozilla-hub.atlassian.net/browse/RELOPS-1164

https://github.com/facebook/watchman/releases/tag/v2023.05.01.00

watchman.pkg drops

watchman 
watchmanctl

into /usr/local/bin and

libcrypto.1.1.dylib
libevent-2.1.7.dylib
libgflags.2.2.dylib
libglog.0.dylib
liblz4.1.dylib
libpcre2-8.0.dylib
libsodium.23.dylib
libssl.1.1.dylib
libz.1.dylib
libzstd.1.dylib

into /usr/local/lib/

These binaries should work for now but its worth noting that this the last binary release for macOS. Other install methods are available via homebrew, but that presents challenges (for one we dont install homebrew) and my initial testing via the brew pkg method were unsuccessful

Hmm, do we need to update hgrc to enable the plugin? I think we might.

do you think that would cause these failures?
