Apt-rpm installation not working

["RICOTTA, FEDERICO [AG-Contractor/5000]" <federico ricotta monsanto com>]

Hi every body:

Like I said in the subject, I'm trying to install apt in RH9, using this:

'rpm -ivh apt-0.5.5cnc6.fr1.rpm'

The first message I get is that I don't have the pubkey
after that apears a message saying 'Warning: user dude could not be found: using root'
                                   'Warning: group dude could not be found: using root'

this repeats about 10 times
and then shows

'Preparing:          ############################## 100%'

and returns to the prompt...
The result is: "nothing is installed"
Tell me if I'm missing some kind of data' (I'm in the office right now, running win2000)
Any clues or pointers?
TIA
