Forum OpenACS Development: psql:acs-install.sql:170: ERROR:

Hi, I already posted it in other thread (OpenACS4.x/Postgres7.x installation guide) maybe that isn't the right place... So:
I'm using RH 7.0

• Unistalled old postregs7.0.3 and installed postgres-7.1*rpm distribution.
• Installed Aolserver3.2+ad12
• Changed the configuration section for postgres driver
  

  # section added for openacs 4.x
  ns_section ns/db/driver/postgres
      ns_param   pgbin        /usr/bin
  

• Compiled ns_xml module
• Started aolserver with ./bin/nsd -k .tcl
• Start installation from http://:

Then the installation stop with the message:

psql:acs-install.sql:170: ERROR:  Function
'acs__magic_object_id(unknown)' does not exist
        Unable to identify a function that satisfies the given
argument types
