[Openmcl-devel] Can't access Interface Database files from application bundle

Glad to help! I'm not sure why the other approach doesn't work, but, 
IMHO, the logical-pathname stuff is much cleaner and more flexible 
(imagine you've got multiple different ccl:foo things you want to 
include). Also, I imagine you're doing a (ccl:use-interface-dir ...) 
somewhere, right?

The lisp-paste with my original example is at:
