Weird. Those typos (missing semicolons) don't cause installation problems with PG 8.0.x. Regardless, I've commited the fix to oacs-5-2.
However, I gather from what people like Don have said, that you're going to run into trouble with PG 8.1 at other points with other packages because of the toolkit's use of tree_sortkeys and changes in how PG implements things in 8.1 compared to 8.0. Perhaps some other issues too. But it's not merely a problem with two missing semicolons in one create sql script.
