Installing the required Perl modules

Three Perl modules are required on the install machine.

These are:

Mail::Address
XML::Parser
JSON-2.90

Note: You only need to perform this procedure on the install machine. These modules aren't required on any other nodes.

To install the required Perl modules:

Install Mail::Address:
1. Download Mail::Address from http://pkgs.fedoraproject.org/repo/pkgs/perl-MailTools/MailTools-2.14.tar.gz/813ae849683367bb75e6be89e4e8cc46/MailTools-2.14.tar.gz.
2. Extract MailTools-2.14.tar.gz:
```
tar -xvf MailTools-2.14.tar.gz
```
  This creates a directory called /MailTools-2.14.
3. Go to /MailTools-2.14 and run the following commands to install the module:
```
perl Makefile.PL
make
make test
sudo make install
```
