Thanks! Yes I used the print trick prior to my post, but forgot to mention that is how I figured out where it is hanging. Also, yes I am using strict/warnings. I get a timeout error: Could not login to SFDC: 500 Can't connect to www.salesforce.com:443 (timeout)

The server where it works: Red Hat Enterprise Linux Server release 6.7

The server where it doesn't work: Red Hat Enterprise Linux Server release 5.11

Here is the code:

#!/usr/bin/perl
    use strict;
    use warnings;
    use Storable;
    use POSIX qw(strftime);

# Parameter/host file
    require "host.pl";

# Environment Proxy
    our $http_proxyurl;
    our $http_proxyprt;
    $ENV{HTTPS_PROXY} =  $http_proxyurl . ':' . $http_proxyprt;

    use WWW::Salesforce;
        
    our $sfdc_username;
    our $sfdc_password;
    our $sfdc_secrtokn;
    our $sfdc_instance;
    our $sfdc_soap_url;
    our $sfdc_versnnum;
    our $oper_emailadd;
    
    my  $sfdc_loginatt = eval { WWW::Salesforce->login(
                                    username => $sfdc_username,
                                    password => $sfdc_password.$sfdc_s
+ecrtokn,
                                    serverurl=> 'https://' . $sfdc_ins
+tance . '.' . $sfdc_soap_url . $sfdc_versnnum ); };
        if ($@) {
            warn  "Could not login to SFDC: $@";
            die;
        };
