Warning in CLI while loading modules

These lines should not be there.

To Reproduce Steps to reproduce the behavior:

1. install pf on debian12
2. run command line with bin/pfcmd something with argument or submodule
3. See error

So this is coming from: https://github.com/inverse-inc/packetfence/blob/feature/debian12/lib/pf/cmd/subcmd.pm#L48 which can be split in two steps:

use Data::Dumper;
        eval {
            if ( is_loaded($module)) {
print("\n"); # we do not care yet, no issue at this point
            } else {
print("\n");
print("nope b\n");
print Dumper ($module);
print("\n");
print("\n");
                load $module;
print("\n");
print("nope a\n");
print Dumper ($module);
print("\n");
print("\n");

            }
            $cmd = $module;
        };

As result:

root@IP :/usr/local/pf# bin/pfcmd fingerbank

nope b
$VAR1 = 'pf::cmd::pf::fingerbank';

nope a
'pf::cmd::pf::fingerbank'

Usage:
     pfcmd fingerbank <command>

So, something is happening with load of the Module::Load: https://metacpan.org/pod/Module::Load https://metacpan.org/dist/Module-Load/source/lib/Module/Load.pm

We are using the latest version:
