Updating SSL

I have a ReadyNAS Ultra 4 Plus running OS 6.10.8 (latest) with Logitech Media Server (LMS) running as an music streaming app.  The LMS system admin page details my system setup as follows:

• Hostname: ReadyNAS-U4P
• Server IP Address: 192.168.0.191
• Server HTTP Port Number: 9000
• Operating system: Debian - EN - utf8
• Platform Architecture: x86_64-linux
• Perl Version: 5.20.2 - x86_64-linux-gnu-thread-multi
• Audio::Scan: 0.95
• IO::Socket::SSL: 2.002
• Database Version: DBD::SQLite 1.58 (sqlite 3.22.0)

To improve LMS functionality I would like to update SSL from 2.002 to the latest available version.

I saw an earlier post on this (link below), but I would really appreciate a guide on how to actually do the upgrade.

Here is the old post:  https://community.netgear.com/t5/Using-your-ReadyNAS-in-Business/Update-SLL/m-p/2186162

I have the "Shell in a box (SSH)" installed on my ReadyNAS, and so I can run commands as the Root user.

I have also seen where I can download the latest SSL source code:  https://metacpan.org/dist/IO-Socket-SSL

I am just not experienced enough to know what steps and commands to follow in order to perform the upgrade, and I can't find it documented anywhere.  I do hope someone on this forum can help.

Many thanks in advance.
