Some of the Radiator features require Perl modules that may not be part
of the Perl distribution you are using. For example, there is no prebuilt
RPM for Red Hat, or the Windows Strawberry Perl distribution does not
include the required module. In this case, you need to install the module
from CPAN.
On Windows with Strawberry Perl, review
Windows installation before continuing.
You can use the tools the Perl distribution provides.
CPAN stands for Comprehensive Perl Archive Network. CPAN is a
repository of Perl modules including the core Perl itself. You can use
CPAN to search and download Perl modules, view their documentation, source
code and change logs.
You can search CPAN for Perl modules with several methods, for
example:
Perl comes with tools for downloading and building Perl modules
automatically. For more information, see
How to
install CPAN modules 
.
cpan and
cpanm are the common tools, they are run from command
line:
cpan Digest::MD5
cpanm Digest::MD5
If you do not have network access, the general procedure for installing
a Perl module is:
- Unpack the downloaded module in a work area.
tar zxvf Digest-MD5-2.55.tar.gz
- Move to the module directory. See README, INSTALL, and similar files
for additional information.
cd Digest-MD5-2.55
- Create the makefile.
perl Makefile.PL
- Build the module.
make
- Run the tests.
make test
- Install the module.
make install
