I am not sure if what I am attempting is possible but I'll ask any ways. I have a script which performs various checks. This script will be deployed on at least 6 servers. Currently I only require it to use 2 modules, DateTime and DBI; The idea is that it will first check to see if those modules are indeed installed and if they are not, install and load them. I am looking into Module::Load but not sure if it can handle what I am trying to accomplish. I'd prefer not to use a module to do this. What I currently have is the following

#!/usr/bin/perl

use warnings;
use strict;

my $version = `cat /etc/*-release | head -n 1`;
chomp $version;
my ($os) = $version =~ /(Ubuntu|CentOS)/;

my %rhel = (
    "DBI"       => "perl-Class-DBI-mysql.noarch",
    "DateTime"  => "perl-DateTime.x86_64",
);

if ($os eq 'CentOS'){
    foreach my $mod (keys %rhel){
        eval {
            require $mod;
            $mod->import();
            1;
        } or do {
            system("yum install $rhel{$mod} -y");
        }
    }
}

2 issues with this, 1 it does not actually seem to load the module and 2 I don't want the text in STDOUT from the eval.

If any of this makes any sense and you can help I'd love the advice. Thanks in advance

------ UPDATE ------

Seems like I have solved my issue. Here is what I ended up doing

#!/usr/bin/perl

use warnings;
use strict;

my $version = `cat /etc/*-release | head -n 1`;
chomp $version;
my ($os) = $version =~ /(Ubuntu|CentOS)/;

my %rhel = (
    "DBI"       => "perl-Class-DBI-mysql.noarch",
    "DateTime"  => "perl-DateTime.x86_64",
);

if ($os eq 'CentOS'){
    foreach my $mod (keys %rhel){
        eval "use $mod";
        if($@){ 
            system("yum install $rhel{$mod} -y"); 
            eval "use $mod";
        }
    }
}
