Config::Augeas does not compile under Big Sur

First, thanks to all the Perl maintainers on the list!

Second, I'm trying to figure out how to get Config::Augeas installed on 
macos 11.x (aka Big Sur). I successfully installed this module on Mac's 
running 10.x but I'm hitting a wall on 11.x. The module returns an 
undefined Augeas object and then fails the tests run by prove during 
installation:

Someone with more knowledge than me has boiled this problem down and 
reproduce it with some test code found here: 
https://github.com/hakonhagland/perl-augeas-test

I'm wondering if someone with intimate knowledge of changes to how Big 
Sur interfaces with XS and loads libraries might be able to chime in and 
offer some guidance. I'm guessing this problem extends beyond just the 
Config::Augeas module.

Thanks.
