Indeed this step is required for postgresql 8.4.x (you have to install 
this script).
I did not encounter an issue with this script.
I ran

psql -U postgres -d engine -f /usr/share/pgsql/contrib/uuid-ossp.sql

And the script execution went smoothly (this scripts runs instructions 
of create or replace function so it is re-entrant).
Can you please elaborate more on the error you're getting?
