title: Unable to Install Erlang using asdf on OSX 10.15.4
body: <p>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:</p>

  <p>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?</p>
