I indirectly make a lot of use of GDAL which makes a lot of use of proj. I do
all this on a new Macbook pro with Apple Silicon. I manage these things with
homebrew. It was a tiny bit complicated to get homebrew running to take
advantage of the new silicon but I’ve been doing that successfully for a month
or so.
At some point in the past I installed proj@7 from homebrew. That’s now
deprecated but I can’t seem to kill it on my system. Lots of brew uninstall and
install/upgrade commands. I used locate in a terminal and attempted to delete
all the files with proj@7 in their names. I’m currently have this set of
exchanges
gcn@MacBook-Pro-M1X Cellar % brew install gdal
Warning: No available formula with the name "proj@7" (dependency of gdal). Did
you mean proj?

This similarly named formula was found:

To install it, run:
brew install proj ✔

(use "git add/rm <file>..." to update what will be committed)
(use "git restore <file>..." to discard changes in working directory)
deleted: Formula/p...@7.rb

Dropped refs/stash@{0} (cf00995d0160fc9ed0889b664973b1c75a4a5925)
At this point I’m stuck on next steps. I suspect this is not a gdal problem per
se but something in homebrew I’m not understanding.
Any advice greatly appreciated!
