I am new to Elixir, and am running on a Macbook Pro, Monterey 12.5. I am going through a course that uses :observer.start(). When I ran this in iex, I got this output:
iex(1)> :observer.start()
19:39:22.117 [error] ERROR: Could not find 'wxe_driver.so' in: /Users/matt.farabaugh/.asdf/installs/erlang/23.3.4.4/lib/wx-1.9.3.1/priv

When I used asdf to reinstall erlang, I see a message related to wxwidgets:
* wx : wxWidgets was not compiled with --enable-compat28, wx will NOT be useable
* Can not link the wx driver, wx will NOT be useable
However, when I look at the Homebrew formula for wxwidgets, which is installed, I see that compat28 has a line like this:
"--enable-compat28",
So I tried reinstalling wxwidgets with the --build-from-source option, and then tried to reinstall erlang. I got a new error, with partial log below from ~/.asdf/plugins/erlang/kerl-home/builds/asdf_23.3.4.4/otp_build_23.3.4.4.log
