in thread module-starter command not found after installation
This command will just unset some environment variables and restore PATH in your current shell. You need to edit your shell rc file (usually ~/.bashrc, check root's too) to reset changes local::lib made. You may also need to edit CPAN config, try grep -r perl5 ~/.cpan (maybe as root) to check whether you need to do it.
You can also install modules as normal user (to ~/perl5) if you allow local::lib to create the overlay.
Sorry if my advice was wrong.
