This must be the same problem as #43746 because it also uses Boost 1.86: https://github.com/apache/arrow/actions/runs/10481257647/job/29030430952#step:12:225

-- Found Boost: /opt/homebrew/lib/cmake/Boost-1.86.0/BoostConfig.cmake (found suitable version "1.86.0", minimum required is "1.64") found components: system filesystem

#43766 will fix this too.

I close this as duplicate of #43746.
