If you are getting a ‘Can’t locate CPAN.pm in @INC’ error while opening cpan, you have not installed Bundle::Cpan. You can do that without Cpan - using yum
yum install perl-CPAN
Install Perl modules on a linux system - must be connected to the net
perl -MCPAN -e shell
If CPAN is not installed use this command to install it in a RedHat/Fedora system.
yum install perl-CPAN
If you are doing this for the first time, there will be a configuration procedure.
install XML::Parser
