Installing Encode.pm for Perl 5.6.1

Hi Team,

We have a legacy Perl application which was developed using Perl 5.6.1.

I would like to Install Encode.pm which is a pre requisite for
Cache::Memcached.

When i tried to install Encode.pm for Perl 5.6.1 it fails as it compatible
with Perl 5.7, Is there any other way to install it for Perl 5.6.1..?

Appreciate your kind help on this.

WIth Regards
