How do I install a module for Perl using the WHM interface?
You can install a Perl module by going to WHM's Home »Software »Install a Perl Module. Once here, search for the module by name. Once you have found the module you require, click on "Install."
Once you have clicked "Install" a new page will load. Please allow the installation to finish.
For more details, the documentation for using this function of WHM can be found here.
