Roy,
From a related prior post Roger shared this link to rgdal-1.5-9, http://spatial.nhh.no/R/rgdal/ . I followed discussions
from the 'sf' github readme and purged all prior proj/geos/gdal iterations that have lingered around over the past five
years and built them from source on ubuntu 20.04. This upgrade to 20.04 was perhaps my first mistake in a month
long effort to bring back my full spatial capabilities as it doesn't become the official LTS until sometime mid this month.
I don't know how Anaconda packages and may require sym links or copying files from down in the depths to visible,
but it worked before and can be made to work again.
HTH-
Chris

Dear Roger,
Many thanks for the effort keeping rgdal up-to-date with proj6.
I'd like to report that I am unable to install rgdal 1.5.8 on my macOS
system. I am reporting this error here on the list because I thought it
would be the best channel in terms of reaching future users experiencing
the same error. Please apologize if my rationale is not right, and
ignore this message.
GDAL was installed via MacPorts and is at its latest version, 3.1.0 (at
the time of this writing). Proj6 has also been installed via Macports.
This is how I am trying to install it:
export PKG_CONFIG_PATH=/opt/local/lib/proj6/lib/pkgconfig
R
install.packages('rgdal', type="source", configure.args=c(
'--with-proj-include=/opt/local/lib/proj6/include',
'--with-proj-lib=/opt/local/lib/proj6/lib'))
and this is the output I get:

I found this error to be quite mysterious, and could not find any
previous discussion about it.
Try to avoid googling, it is usually misleading. Running ./configure in
the untarred source package directory, and running ./configure --help to
show the arguments to configure can be much more helpful. Crucially, they
are up to date, while most search hits are old, and they are ordered by
hit counts, which is certainly no guarantee of precision.
Are you familiar with it? Is there any other argument that I can pass to
install.packages to solve it?
Try not setting configure arguments and let pkg-config proj do the work if
you feel you can trust it. If, however, you have multiple installs of GDAL
and/or PROJ, the proj.pc file may point to a deleted install. Download and
untar the source package, and run just ./configure with its argumments, or
setting PKG_CONFIG_PATH= until you find a recipe that works that far.
Roger

With sp 1.4-2 and rgdal 1.5-8, those using GDAL 3 and PROJ 6 (including
users of the CRAN Windows binary when it comes) will be part of the big

You will see lots of warnings, they should grab your attention, that is
what they are for. We need your attention to be as sure as we can be that
your results - if affected by the transition - have been checked by you.
I plan to flip the warnings to default off from rgdal 1.6-*, and sp 1.5-*.
In some weeks but before flipping the defaults, I'll follow up showing
ways of muting them, but we really need to be confident that this
necessary and future-proofing change isn't silently destroying your work
first. So please don't treat the many warnings as just pesky and nagging -
they are priming your immune system to check for unwanted consequences of
your legacy CRS representation choices.
I'd also like to thank the maintainers of packages importing
from/depending on sp/rgdal for largely positive responses to issues raised
and emails sent, often less polite than they might have been, but grabbing
attention was more important. From over 70 broken reverse dependency
packages we are now well under 20, and I've contacted all of those, with
only a couple not responding. Edzer has seen similar responsiveness for
the parallel migration of sf.
Enjoy!
