I am running into an issue that I haven't previously had with over 6+ months of using asdf on osx. I need to install Erlang 21.3.7.1 and when I do I get this error output from the console that I honestly don't know how to solve:
Me@My-MacBook-Pro:~/Code/codebase|master

Nothing I found on the Erlang/Elixir/asdf forums was particularly helpful. asdf was installed with homebrew. I can install the ref:maint build and change my .tool-version to match but that sets off a whole slew of other issues with Crypto and openssl not being found even though they're installed. Anyone have an idea or two?
It's not possible to build Erlang 21 on Catalina (10.15), according to the comments in this bug report. You can use release 22.3.1 or later.
If you need to use an older Erlang version, you could try applying this change on the Erlang 21 source code.
