Hi David,

Chiming in only because you and I have MBPs of similar (identical?)
vintage. I've been recently playing with a module and had to update
CPAN. I ran into problems installing the 2 Mac-specific modules
File::HomeDir  and  Mac::SystemDirectory , so maybe you can check if
they're up-to-date for you.

#CPAN output:
Failed during this command:
 ETHER/Mac-SystemDirectory-0.13.tar.gz        : make NO
 REHSACK/File-HomeDir-1.006.tar.gz            : make_test NO one dependency
not OK (Mac::SystemDirectory)
 ANDK/CPAN-2.28.tar.gz                        : make_test NO one dependency
not OK (File::HomeDir)

Possible "Big Sur" connection/resolution here:

HTH, Bill.
