I'm having problems trying to use modules downloaded from CPAN, but always the same problem for any module (I've tried Term::ReadKey, Crypt::Passwd, and Digest::MD5). After downloading the modules and putting each in /var/tmp/perl (i.e.- /var/tmp/perl/Digest/MD5.pm, /var/tmp/perl/Crypt/Passwd.pm, /var/tmp/perl/Term/ReadKey.pm) and then adding 
use lib '/var/tmp/perl';
use Digest::MD5;

to a script that previously worked, without making any other changes to the script, I now get the following error: 
Can't locate loadable object for module Digest::MD5 in @INC (@INC cont

Then, trying to execute the module directly: 
perl /var/tmp/perl/Digest/MD5.pm

I'm a programmer, not a systems administrator, so I don't have much (any) experience installing and configuring Perl, I just want to be able to download and use modules so I don't have to code everything from scratch. Can anyone offer any help on what I'm doing wrong?
