Don't forget the 1 on the end.

Sorry if this is too obvious, but you mention that the config component returns not true. A quick look at require will show that:

The file must return TRUE as the last statement to indicate successful execution of any initialization code, so it's customary to end such a file with `` 1;'' unless you're sure it'll return TRUE otherwise. But it's better just to put the ``1;'', in case you add more statements."

Which would be tricky to deduce, i agree, but not hard to look up...
