#3 File permissions check.

[Wendall Cada]

The file permissions check on the installer make the
install fail. However, the tables created aren't
removed, which would force the user to delete the
tables to reinstall at all. It has been the common
practice to simply warn the user of the directory
permissions problem and finish the install. If you want
the current behavior to be the same, you'll need to
drop the tables from the database when the error is
generated.
