Why can't you load in the primary library lib folder? – ssr1012

You didn't specify where Fapatching.pm is located, so let's say you have the following (pretty common) directory structure:

$project_home/bin/fapatch-prereq.pl
$project_home/lib/Fapatching.pm

You can solve this by adding the following to the script:

use FindBin qw( $RealBin );
use lib "$RealBin/../lib";

Adjust to your needs.

Adding a use lib statement to the script will add the directory to @INC for that specific script. Regardless who and in what environment runs it. Referred from here.

use lib '/folder1/folder2/package';
use Fapatching;

Thanks to Author: Gabor Szabo. I am not recommeded however I referred here.
