I am getting this when I do asdf erlang install 24.0:

Latest macOS and I am pretty sure I have libraries here: /usr/local/opt/openssl@1.1/lib (notice the trailing /lib) so maybe the script is looking in the wrong place?

@dimitarvp, it worked when building from source for me. So I wonder if this is an issue with kerl? 
Next week!

How can I check? I have a daily CRON script that updates asdf itself and all installed plugins so I shouldn’t be using anything old there. But as for kerl itself, no idea how to check?
I have finished reading the release notes. This section seems to be relevant:
OTP-16882 Application(s): crypto
Add /usr/local/opt/openssl to the openssl configure
search path. This path is where some tools on OS X
place openssl.
OTP-17254 Application(s): crypto, erts
Related Id(s): ERIERL-618, GH-4230
The configure scripts in crypto and erts now fail if a
requested feature cannot be enabled.
Large parts of the configure script of crypto have been
rewritten with various improvements and bug fixes. It
is now better at finding usable OpenSSL libraries, but
will in the following cases fail to detect OpenSSL
libraries where it previously sometimes detected the
libraries by chance:
-- OpenSSL installations with include directory and lib
directory parts installed in different base
directories. In order to detect such installations
after this change, the user must explicitly specify the
locations using the --with-ssl=<path> and the
--with-ssl-incl=<path> configure command line
arguments.
-- When building with old gcc compilers or other
compilers on Debian derivatives with multiarch
directories under the lib directory. In order to detect
such installations after this change, the user must
explicitly specify the multiarch directory name using
the --with-ssl-lib-subdir=lib/<multiarch-dir> configure
command line argument.

After scanning the forum and reminding myself of how I was doing things in the past (when straight up asdf install didn’t work), I ended up doing this (and a few variations) but it didn’t work either:
$ KERL_CONFIGURE_OPTIONS="--with-ssl=$(brew --prefix openssl)/lib --with-ssl-incl=$(brew --prefix openssl)/include/openssl --enable-dynamic-ssl-lib --enable-wx" asdf install erlang 24.0
asdf_24.0 is not a kerl-managed Erlang/OTP installation

I was having similar issues which were resolved by adding --disable-parallel-configure to my KERL_CONFIGURE_OPTIONS as suggested by the reporter here:

Thank you. That got me a bit further:
$ KERL_CONFIGURE_OPTIONS="--disable-parallel-configure" asdf install erlang 24.0

Macos 10.15.7 here. Build fails for both normal asdf install and using the suggested KERL_CONFIGURE_OPTIONS. I could install all the RC versions using asdf without any problems.
Does anyone know how to make Erlang’s Observer/WX work on 24.0? (I’m running on Ubuntu 20.04)

I believe it needs wx 3.0, what is your version?
Yes, I am afraid I spoke too soon 
I also only get as far as you do…
