Well, I couldn't figure out how to make it TAINT safe. Taint complains pretty much any time you try to execute code you are importing from somewhere else (at least, that's my understanding).

What you should be doing is eval'ing the configuration file. Below, I read in the config.pl file into a scalar, eval it, and pop the results into the $conf hash reference.

#!/usr/bin/perl -w

use strict;

my $config_file=(""); # declare this way to prevent warnings

open(RE,"config.pl") || die("cannot open config.txt");
while(my $line=<RE>){
  $config_file .= $line;
}
close(RE);
my $conf = eval($config_file); # you can look at $@ after 
                       #this to see if eval had any errors!
print $conf->{'var1'}, "\n";
print $conf->{'var2'}, "\n";

If you have a LOT of configuration information, you might want to look at something like XML::Simple, which will allow you to create a clean* looking configuration file and use it in your script pretty easily.

* XML is a two-edged sword. It CAN be clean, but you can make it look ugly if you try :)
