How to use third party Perl library (ExifTool)?

[firenze]

Hi, I just set up an account and I'm having trouble using this library through a .cgi script.

Here's what I've done:

1. Copied ExifTool into my public-html/ftpuser/ folder
2. Tried to run a script from the same folder (scr.cgi) with the following:

#!/usr/bin/perl -s
use Image::ExifTool qw(:Public);
my $exifTool = new Image::ExifTool;

but I'm getting the 500 Internal Server Error
Obviously the lib is not installed. So I tried:

use lib ''/home/firenze/public_html/ftpuser'';

But still the same

What I'm trying to do is to have a .cgi script that uses this lib and displays the exif data, but I can't find a way to do that. Help really appreciated. Thanks.
