Okay, I've figured out the previous issue. The openssl package
configure script dies if it doesn't have openssl version 3, while
install.libs() provides version 1.1.
So I followed the advice to install from Homebrew, and the configure
succeeded, but the install still failed:
** testing if installed package can be loaded from temporary location
Error: package or namespace load failed for ‘openssl’ in dyn.load(file, DLLpath
= DLLpath, ...):

'/Users/murdoch/R/R-devel/library/00LOCK-openssl/00new/openssl/libs/openssl.so':

Error: loading failed

Any suggestions?

Homebrew >=4.1.0 (shallow or no git repository)
Using PKG_CFLAGS=-I/usr/local/opt/openssl/include

Configuration failed because openssl was not found. Try installing:
* deb: libssl-dev (Debian, Ubuntu, etc)
* rpm: openssl-devel (Fedora, CentOS, RHEL)
* csw: libssl_dev (Solaris)
* brew: openssl (Mac OSX)
If openssl is already installed, check that 'pkg-config' is in your
PATH and PKG_CONFIG_PATH contains a openssl.pc file. If pkg-config
is unavailable you can set INCLUDE_DIR and LIB_DIR manually via:
R CMD INSTALL --configure-vars='INCLUDE_DIR=... LIB_DIR=...'
I did install the openssl lib using Simon's install.libs() function from
https://mac.r-project.org/bin/, and I do have pkg-config installed in
/opt/R/arm64/bin and I see this:
$ pkg-config openssl --cflags
-I/opt/R/arm64/include
So I don't know where the openssl config is finding the Homebrew info.
Can someone suggest what I need to do to get this to work?
