It looks like you've already tried to install the package once before - acs_views and acs_view_attributes are part of AOM. I would run the drop script: packages/acs-object-management/sql/postgresql/acs-object-management-drop.sql first, then run the metadata updates I mention in the other thread. The data model install script creates default attribute views for all objects but it chokes when there is bad metadata. The issues mentioned in the other thread are probably common if you have .LRN installed. Copying those data model updates and running them on your system (on test system first!) would probably do the trick but you could also run the datamodel__acs_object_type_check test case at /test/admin as Jeff indicated to see what's going on in your specific install and clean up your object metadata as necessary. Let us know how you make out.
