i know that i am reusing the same functions over and over
So what he (or she?) really needs is just a package, not really a fully-blown OO interface. Remember the KIS rule!

Let's say you have a function for logging and a function for carrying out some kind of calculation. Make a file called whatever.pm, and in it include:

package whatever;

sub log {
 # do logging 
}

sub calculate_something {
 # do calculations
}

return 1;  # Perl insists on this :-)

So in your scripts, you can just do:

#!/usr/bin/perl

# Tells Perl to look in current dir for modules, may not
# be necessary. 
unshift @INC, ".";

use whatever;  # the file must have .pm ext for 'use'

whatever::log("Log file entry"); 
$answer = whatever::calculate_something();
