Unknown PerlIO layer "encoding"

[dbcooper]

When using Perl::Tags::Naive on my system (http://hastebin.com/otemiyidar.vhdl) , I receive the following warnings:

Unknown PerlIO layer "encoding" at /usr/local/share/perl/5.14.2/Perl/Tags.pm line 213.

This is (apparently) resolved by adding the following line to the Tags.pm source

use PerlIO::encoding;

I don't know what else this might mess up so I'm reporting this as an issue rather than a source modification. Diff(1) output follows.
