If I understand Faré correctly, you define output files normally, but 
then I believe you need to do the following:

```
(defmethod input-files ((op compile-op) (file org-source-file))
     (output-files (asdf:make-operation 'tangle-op) file))
```

If I'm right, this will ensure that `compile-op` sees the translated 
pathnames for the lisp files, instead of looking in the source 
directory.
