perl issues on macOS Catalina

[ctaggart]

I ran a creduce on my Mac for ctaggart/octh#36 for 76 hours and it created 10 bug reports. I skipped several steps that looked like they would also fail. I'm running macOS 10.15 Catalina and it comes with perl v5.18.4 and some additional security. After seeing fink/fink#201, I installed perl v5.30.0 from brew and started creduce again. It has been running all night and so far so good.

Bundled perl was released in 2013:

Camerons-MacBook-Pro:creduce cameron$ /usr/bin/perl --version

This is perl 5, version 18, subversion 4 (v5.18.4) built for darwin-thread-multi-2level
(with 2 registered patches, see perl -V for more detail)

Perl from brew install brew is up-to-date:

Camerons-MacBook-Pro:creduce cameron$ which perl
/usr/local/bin/perl
Camerons-MacBook-Pro:creduce cameron$ perl --version

This is perl 5, version 30, subversion 0 (v5.30.0) built for darwin-thread-multi-2level
