Want is up to date (0.25) just means that cpan found the .pm and found its version to the latest. It doesn't run any tests. It doesn't even try to load the module.

The first error you got indicated that the module is improperly installed. Specifically, the compiled component of the module is missing.

I suspect that Want is not installed at all. cpan simply found the Want.pm in the current directory.

The solution: Change directory to one that doesn't contain Want.pm.
