First look at the obvious. buildParentSQL can print stuff before buildSQL if the loop in buildSQL doesn't execute. Are you sure that (keys($tables{$table})) is what you want in there ? Hard to tell w/o knowing what $tables is, but it looks a little fishy.

Such problems in general are easy to resolve with extra printouts. In the beginning of every function insert a printout of "foo called" (possibly with its arguments) and in the end a printout of "foo returns" (possibly with what it returns). Then, run on a small example - this will sure clear things up for you.
