　　1. Check whether you have 'perl-CPAN‘ package installed in your system.
　　For checking ‘perl-CPAN’ package run following in your shell.
　　[root@host13 ~]# rpm -q perl-CPAN
　　If perl-CPAN package is installed, you will get the output like this
　　perl-CPAN-1.9402-116.fc13.i686
　　else, you will get output like this
　　package perl-CPAN is not installed
　　and that the case you need to install it. You can install it via using yum, yum install perl-CPAN or from rpm, from “rpm.pbone.net” you can obtain “perl-CPAN rpm’s”.
　　2. Running the command "perl -MCPAN -e shell" will brought you to a CPAN command prompt
　　[root@host13 ~]# perl -MCPAN -e shell
　　Terminal does not support AddHistory.
　　cpan shell -- CPAN exploration and modules installation (v1.9402)
　　Enter 'h' for help.
　　cpan[1]>
　　Note : If this is the first time you’ve run CPAN, it’s going to ask you a series of questions – in most cases the default answer is fine.
　　If you got an error given below, then you need to confirm the "perl-CPAN" package’s existence in the sytem
　　Can't locate CPAN.pm in @INC (@INC contains: /usr/local/lib/perl5 /usr/local/share/perl5 /usr/local/share/perl5 /usr/lib/perl5 /usr/share/perl5 /usr/share/perl5 /usr/lib/perl5 /usr/share/perl5 /usr/local/lib/perl5/site_perl/5.10.0/i386-linux-thread-multi /usr/local/lib/perl5/site_perl/5.10.0 /usr/lib/perl5/vendor_perl/5.10.0/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.10.0 /usr/lib/perl5/vendor_perl /usr/lib/perl5/site_perl .).
　　BEGIN failed--compilation aborted.
　　3. From this command prompt you can install the perl modules.
　　Examples:
　　cpan[1]> install MIME::Entity
　　cpan[1]> install MIME::Parser
　　cpan[1]> install Crypt::PasswdMD5
　　cpan[1]> install Term::ReadPassword
　　cpan[1]> install Crypt::CBC
　　cpan[1]> install Crypt::Blowfish
　　cpan[1]> install Daemon::Generic
　　cpan[1]> install DateTime
　　cpan[1]> install SOAP::Lite
　　Alternative for second and third step.
　　[root@host13 ~]# perl -MCPAN -e 'install HTML::Template'
　　[root@host13 ~]# perl -MCPAN -e 'install MIME::Entity'
　　[root@host13 ~]# perl -MCPAN -e 'install Crypt::PasswdMD5'
　　[root@host13 ~]# perl -MCPAN -e 'install Term::ReadPassword'
　　[root@host13 ~]# perl -MCPAN -e 'install Crypt::CBC'
　　[root@host13 ~]# perl -MCPAN -e 'install Crypt::Blowfish'
　　[root@host13 ~]# perl -MCPAN -e 'install Daemon::Generic'
　　[root@host13 ~]# perl -MCPAN -e 'install DateTime'
　　[root@host13 ~]# perl -MCPAN -e 'install SOAP::Lite'
