As the log file shows, the Unicode::Collate module is not found.  I don't
know what the solution to this is.

It is meant to be included (in the "perl core") with perl 5.26.3 (the perl
version reported).

https://perldoc.perl.org/5.26.3/modules

But evidently we can't rely on this.

You can also run "corelist -a Unicode::Collate" to confirm it is a core
module.

As it is supposed to be a core module, then there is probably not a need
to make the program work without it.

It's possible that a distribution does something to install fewer packages,
but I found the following page (via Google) that lists a Unicode::Collate
package as a dependency of Perl, on Centos 8-stream:

http://www.rpmfind.net/linux/RPM/centos/8-stream/appstream/x86_64/Packages/perl-5.26.3-420.el8.x86_64.html

Is it possible that Unicode::Collate is installed on the system somewhere
but that we aren't finding it due to incorrect @INC?

Or is there any reason why Unicode::Collate wouldn't be installed?  Was
Perl installed in an unusual way on this system?
