Exporter::Lite is an alternative to Exporter, intended to provide a lightweight subset of the most commonly-used functionality. It supports import(), @EXPORT and @EXPORT_OK and not a whole lot else. Exporter::Lite simply exports its import() function into your namespace. This might be called a "mix-in" or a "role". If you have local Perl set up and override the "install base" parameter through the $PERL_MB_OPT or $PERL_MM_OPT variables then the build will fail.
