What's the question?

If it was is a bug you should file a bug report.

But my guess is that you meant config which is lower case.

Edit

Ugh ... That's not the config I meant and a rather unfortunate naming ...

I suppose the Config.pm that ships with core Perl is simply not mirrored on CPAN, try Config.

Update

Which makes sense since the hardcoded values inside the %Config hash highly depend on the actual built with config.sh . IOW it's more of a glorified log with interface created during the built of the perl.exe ...

Installing from CPAN wouldn't make sense.
