Installation using the Perl Shell

Login to your command line as root and run the following command to start the Perl shell:

perl -MCPAN -e shell

If you run the Perl shell for the first time you will be asked some questions. In most cases the default answers are ok.

Please note: If you run a firewall on your system you might have to turn it off while working on the Perl shell in order for the Perl shell to be able to fetch the needed modules without a big delay. You can switch it on afterwards.

Run the following commands to upgrade CPAN

install Bundle::CPAN

Accept defaults at all prompts

reload cpan

Run the following commands to install the modules needed by SpamAssassin:
