Well nice tutorial but I have a question, I did all you explain and I have Mountain Lion.. but at the end when I launch < perl example.pl > an error message appear like this:

DBD::oracle initialisation failed: Can't locate object method "driver"
+ via package "DBD::oracle" at /System/Library/Perl/Extras/5.16/darwin
+-thread-multi-2level/DBI.pm line 808.

Perhaps the capitalisation of DBD 'oracle' isn't right. at Modulos/lib
+/ConectarDB.pm line 17.

and this is ConectarDB.pm

#!/usr/bin/perl

package ConectarDB;

use strict;
use DBI;

# variables BD
my $db_user = "example";
my $db_pass = "example";
my $host_name = "example";
my $db_name = "example";

# vars
my $q_string = "DBI:oracle:host=$host_name;database=$db_name";
sub connect{
return (DBI->connect ($q_string, $db_user, $db_pass, {PrintError => 0,
+ RaiseError => 1}));
}
1;

So, I try again, but it never works, can you help me??
