It sounds like you have a broken or incomplete puppet installation. Hiera
is deeply integrated with Puppet 3, and in particular with resolving
unspecified class parameters. It is not an optional third-party library as
it was in Puppet 2.x and earlier. PuppetLabs provides it in a separate
package, however, which might lead you to think that you don't need to
install it.
That does not mean you have to put anything in a hiera data store, or even
configure one (as far as I know), but it needs to be there because in
Puppet 3, the master tries to fill in parameter values via hiera before it
falls back to default values specified in the class definition. (That
behavior is awesome, btw.)
