Yes, it's hardware dependent:

https://docs.brew.sh/Installation
"This script installs Homebrew to its preferred prefix (/usr/local for macOS
Intel, /opt/homebrew for Apple Silicon and /home/linuxbrew/.linuxbrew for
Linux"

Maybe we should rely on PATH, rather than hardcoding OS dependent locations?
Or at least fall back to seach binaries in PATH? Seems pretty odd to hardcode
all these locations without a way to influence it from outside the test.

There has to be something similar to python's shutil.which() in perl.
