It seems that the most recent version of patch in homebrew no longer
provides automatic access to a binary "patch" (which I think it used to
do); instead it says
If you need to use it as "patch", you can add a "gnubin" directory
to your PATH from your bashrc like:
PATH="/opt/homebrew/opt/gpatch/libexec/gnubin:$PATH"
If I make that change to PATH, then I see
% patch --version
GNU patch 2.8
Copyright 1989-2025 Free Software Foundation, Inc.
Copyright 1984-1988 Larry Wall
but Sage doesn't find it and insists on building its own patch. The
top-level config.log file shows that this directory is in PATH, but it says
## ------------------------------------------------------ ##
## Checking whether SageMath should install SPKG patch... ##
## ------------------------------------------------------ ##
real_configure:46409: checking for GNU patch >= 2.7.0
real_configure:46495: result:
real_configure:46521: no suitable system package found for SPKG patch
