G'day kapqa,

Welcome to the Monastery.

You're a bit late to the party (by about six months). I started this thread back in January. I was asking about any Perl issues prior to upgrading. As reported, the upgrade was successful; and continues to be.

I suspect you may have posted in the wrong place: maybe after searching for "Perl Sierra issues" or something like that. This looks like it should probably have been a new question; posted in "Seekers of Perl Wisdom".

What you've posted is very difficult to read. Before posting again, please see "How do I post a question effectively?" and follow its guidelines; in particular, please ensure all code, data and program output is posted within <code>...</code> tags. Also see "How do I change/delete my post?": you can fix the problems with your current post.

I gave up trying to read your entire post; however, this (very near the start) stood out:

"... install ... with System Perl ..."

As a general rule, avoid using the system Perl: it's provided by the OS for the OS. When you install modules you run the risk of breaking some part of the OS; when you upgrade the OS, there's a good chance the current Perl version will be removed, a new version installed, and all the modules you installed lost. Instead, use Perlbrew: I've been using this for many years and can recommend it.
