Installing from CPAN -- YAML

Hi,

when installing a module from CPAN I always get the hint that YAML is 
not installed.

To solve the problem I tried to find YAML on CPAN and found dozens of 
pages with YAML.
Scanning the entries I detected CPAN::Meta::YAML. Its documentation 
seems to indicate that that is what I need.
I installed it but still get the message
  'YAML' not installed, will not store persistent state.

So what should I install to satisfy  the 'installer '?

Thanks for any hints.
