Hi Ingo, cpanm is certainly the best tool for installing Perl modules! But if you’re in a package-managed environment and want to use the system Perl (which is understandable, it’s very stable), then current best practice is to not install any non-package-managed modules in the system location. Instead, you should use a local::lib as Zaki said, so that your personally-installed modules overlay any system ones. In particular, if you find yourself using “sudo” to install Perl modules off CPAN, that is a sign of poor practice.
Another benefit of this strategy is that because you install modules as your normal user, it has access to all your normal environment. There are also security benefits.

Yes, that is exactly the issue. The question to me is rather, if this is desired. Who runs an X session as root ? Isn't using cpanm the way to maintain Perl modules these days? I will open an issue and I have a hunch this could easily be caught during build.
