I installed latest 8-x.dev, dated 5/19, on OS X 8.3 on macbook. In install process, after choosing SQLite as database, I get above message after clicking "Save and Continue". This is my normal process for building a 8-x install. Done it a hundred times. All permissions appear OK, no error messages in apache error log.
