'Errors installing rgdal MacOS - still

There have been many posts regarding problems installing the rgdal package. I've been through lots of them, have tried many of the recommended solutions, but still am having problems. I'm using R4.0.3 on a Mac under OS10.15.7 (Catalina). I use MacPorts for package management. I included the R command I used and the results below, but will highlight what seem to be the problems first:

  1. Error "Failed to locate 'svnversion'. I don't understand this because the previous line in the output reads "checking for /usr/bin/svnversion... yes" and using the terminal "which svnversion" yields "/usr/bin/svnversion". The subsequent message about the command line tools has been discussed elsewhere and I have followed the recommendation to remove the COMMAND_TOOLS directory and install the standalone version; this makes no difference.

  2. gdal-config? It exists and is executable, but this text "cat: inst/SVN_VERSION: No such file or directory" appears before the system answers "yes" to the check of gdal-config usability. Looking for that particular message across the net yielded nothing helpful (to me, at least).

  3. pkg-config proj? I installed proj using MacPorts

    % sudo port install proj

Password: ---> Cleaning proj ---> Scanning binaries for linking errors ---> No broken files found.
---> No broken ports found.

But the system seems to be looking for proj.pc. What is that?

  1. pkg-config: command not found but

    % which pkg-config

/opt/local/bin/pkg-config

I've been playing with this for days and would really appreciate some help, even it is just pointing me to a previous post I may have missed.

From within R I issue the command

install.packages("rgdal", type="source", repos="http://R-Forge.R-project.org", configure.args=c('--with-gdal-config=/opt/local/bin/gdal-config'))

Which results in:
