cPanel & WHM servers include multiple Perl environments.
Your Perl modules can use these Perl environments, but they may require certain modifications in order to function correctly.
For instructions to write your own Perl modules or UAPI functions, read our Custom UAPI Modules documentation.
In some cases, particularly if you wrote the script for cPanel & WHM version 11.36 or earlier, you may need to modify a Perl script's shebang line. For more information, read our Modules and Scripts documentation.
