You are dealing with Perl and it needs a module installed (DBD::Oracle). The proper way to do it is to go to CPAN and follow the instructions for installing a new module. You say your computer is 'reachable' from the outside world. I assume that means you have access to the internet. If that is the case try
Code:
sudo cpan -i DBD::Oracle
in a terminal. It should grind away for a while and then it will be installed. If you do not have access to the internet but do from your laptop you can follow the instructions at
Code:

or google for something like 'perl install module without access to internet' and find instructions you can follow. Note that it is possible to install it on another computer and then copy the pm file. But then you have to find where to put it (one of the directories in the @INC list). That may or may not work and is not a recommended solution. You are talking about a more complicated procedure than can really be listed here. Google for Perl instructions, for example 'perl @inc'. You will find better explanations and instructions.
