Yup, that would be perfect.  Concisely explains why /opt/homebrew
and /usr/local are used in the patch.

I presume these are the default for homebrew and users could change
them to what suit their needs, but even then, what you did in your
patch is good; we are merely setting the appropriate defaults, and
those who customize these paths know that they must customize these
paths not just when they install homebrew but when building other
software packages like ours.

Perhaps they have a symlink or something from /sw to /opt/sw, then,
as our Makefile only talks about /sw and /opt/sw

Thanks.
