module not installed: Razor2::Client::Agent ('require' failed)

[Marcin Krol]

Hello everyone,

I'm trying to get Razor2 configured, I get this in spamassassin -D 
--lint output:

[24407] dbg: diag: module not installed: Razor2::Client::Agent 
('require' failed)

But. When I try to install/search for this via CPAN, I get:

cpan> i /Razor2::Client/
No objects found of any type for argument /Razor2::Client/

WTF?

I can't get this module installed into Perl. How do I do that?

Regards,
Marcin Krol
