I'd really like to have only one configuration file so other authorized users aren't installing packages and source to the four corners of the hard drives.
In MyConfig.pm, you can define cpan_home. I am not sure if assigning something global to this key would solve your issue.

Even if everyone uses the same configuration by default, they can nevertheless call cpan -j another_config or even, horrors, install the downloaded modules manually.
