Actually that should work.  If rake is reporting that it cannot build 
your task, then probably one of the prerequisites cannot be built. 
Remember, your rule says that you can build a site_XXX file if the 
following file (or rules to build the following files) exist: 
site_cfg_file(fn), "foo", "bar" and "baz".  I would check to see if 
"foo", "bar" and "baz" all exist.
