Indeed, the problem is that the dynamic binding of project-root is
created inside the `interactive' spec and that spec is not run in the
proper lexical environment (it is run in lexical mode, but in an empty
lexical environment).

A bug in Emacs. Should be fixed on the trunk now.
BTW, please add an "ack--" prefix to your `project-root' var: all
`defvar'd variables should have such a prefix.
