[R-SIG-Mac] Issue installing gdal, sf, rgeos on R 4.1

[Stephen Wild]

Hello,

I am trying to install rgdal, sf, and rgeos on R 4.1 using Apple Silicon
with native arm support. An old email
<https://r.789695.n4.nabble.com/Help-needed-gdal-configuration-to-install-sf-package-in-Mac-OS-Catalina-td4762279.html>
to the R help email list suggested emailing here given the error messages I
am receiving.

When I try to install `rgeos` or `sf` I get the following error:

> configure: error: geos-config not found or not executable.


Full error messages are at the end of the email.

I have followed the instructions here
<https://github.com/r-spatial/sf/issues/1536#issuecomment-727342736> to
install gdal using homebrew. Installation is successful, and running
`gdalinfo --version` show I am running

> GDAL 3.3.1, released 2021/06/28


I have tried uninstalling gdal, reinstalling it, building from source, and
changing the PATH (`export PATH=$PATH:/usr/local/opt/gdal-33/bin`). So far,
no luck. Any help would be appreciated.


Thanks.

Steve
