That particular error is because the bookmark datamodel isn't loaded
by default when you do "psql -f load-data-model.sql". This was left
out because bookmarks weren't ported.
I've committed a port by Alex Sokoloff which you can pick up from the
current CVS tree at sourceforge. I think he's in the final stage of
checking to make sure I committed things correctly (I don't trust me,
no reason he should!) and then intends to make an announcement here.
You can play with it now if you want, though.
