Upgrading to a non-LTS version of Ubuntu means you only get support for a year and then have to upgrade again.
It just goes to show that using the distro's Perl places the choice of whether to upgrade or not out of your control. Sometimes, it's ok to be at the mercy of another company. Sometimes it's not. I can't answer that for you, but asking the question you are asking seems to indicate it's not.
(Previous paragraph rewritten based on better understanding of quoted line.)
Installing a local version of Perl separate from the Ubuntu repos is possible but not ideal.
I think it's *much* better than the alternative. Three major advantages:
- You don't have to run the same OS and OS version on every machine.
- You can upgrade or not upgrade Perl independently of other upgrades to the machine.
- You can test your application with a new installation of Perl while still having the old version installed. This allows you to make sure the machine is setup correctly risk-free, and it allows switching to the new Perl without any downtime.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
