Which is the recommended flavor of Linux to learn perl?
You can use any Linux distribution. I much prefer openSUSE, but that's entirely personal preference. You might be restricted in the future by a computer at $work.
So my advice and main point of this advice: Don't rely on a particular system Perl version.
What I have done is doing exactly this, but you may want to try replacing the "5.16.2" with another version number.
In doing so, you can avoid having to deal with incomplete system Perls. And, when you file a bug report for a Perl issue, you can be sure that it is not a vendor issue.
