but they seem to be hanging around long after they are necessary.

That's impossible. A program can't change the environment of another process. It can change its own, and it can set the starting environment of its children. That's it. That means that the cpan process can't modify your shell's environment.

If you're trying to explain env var found in your shell, start by checking your shell's login and startup scripts (e.g. .profile, .bash_profile, .bashrc).
