authdaemonrc cannot be found

[Ortix]

When i'm trying to install ispcp 1.0.6 i get this error:
ERROR: File '/etc/ispcp/courier/backup/authdaemonrc.system' does not exist !

Here's some info:
Running CentOS 5 on a dedicated Server
followed all the steps in the tutorial provided in the wiki.

Not sure what to do.. I'm somewhat of a newbie when it comes to linux and CLI. I can get around but some steps would be appreciated
