Thanks for this advice.
Something else for me to consider.

However, I personally do not recommend either of these processes this
for enterprise systems. In an enterprise, a different team will
update the OS stack for patching much more frequently than the
application team.
I recommend using the OS provided Perl version and work around any
missing capabilities. Then I recommend that you build/find packages
for all of the CPAN modules that you need and put them in a YUM/APT
repository. Finally, I recommend that you also package your own
application.
We use RPMs which are easy to create. I use the EPEL repository which
has just about all of the Perl package we need. Any others can
normally be built with cpanspec -b. Then for my application-level
RPMs, I have a Makefile that can build my RPM with a simple `make rpm`
command wrapper around tar and rpmbuild.
In our enterprise, we cannot install on a production server directly
from the internet so, `cpan install` would not work anyway and there
is a chance that the code installed is not the version that went
through QA and will most likely not be the same version when the
server needs to be rebuilt in a year.
Remember, any packages that you build are supported by your team. Any
packages that the OS/Security team installs are support by them! So,
try to reuse as much code as possible from the supported OS teams
repositories.

Greetings,
I would strongly recommend leveraging Perlbrew.
I make it a point to never touch "The System Perl" since it is used by
the operating system. It's actually surprising how many command lines
tools are actually perl under the hood, I find it best to leave it alone.
I generally set up a perlbrew instance for my user account and do my
dev that way. Hope that helps!
Best Regards,

I am on Linux Mint now and have the base Perl install:
perl 5, version 26, subversion 1 (v5.26.1) built for
x86_64-linux-gnu-thread-multi
(with 67 registered patches, see perl -V for more detail)
I want to install modules and am having trouble (see far below).
Maybe I can work out that trouble, but I want to ask
you'all how I should set up my system. Just use what
I have (5.26.1) or install PerlBrew and perhaps some
other Perl version?
If I ever do get a module installed, can you tell me where
they will reside? usr/bin has no folders at all.
Oddly, usr/lib does not have a perl folder in it either.
usr/share/perl has a "5.26" directory and "5.26.1" directory.
