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

{:error,

    {:wx, :new, 1, [file: 'wx.erl', line: 115]},
    {:observer_wx, :init, 1, [file: 'observer_wx.erl', line: 107]},

    {:proc_lib, :init_p_do_apply, 3, [file: 'proc_lib.erl', line: 226]}
  ]}}

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
:

Please keep it simple. I’m new to Macs generally.
