ok, as i hunt around i find that version 7.3.2 doesn't have an _int.sql, only an _int.sql.in
and the create_func.sql file is not in version 0.3.1 of the search package.
I managed to get the _int.sql file generated. I ahd to compile the intarray in the contribs directory, this results in the .sql file which ran ok.
however i still don't have the create_func.sql file. where is this in verson 0.3.1? does it exist any more and is this why I'm havong problems?
