It's not entirely clear to me what you want to do, but what about
(defun new-rel-path (rel-pathname)
(merge-pathnames rel-pathname (truename "ccl:")))
Note that that's not enough to be *writeable*, because I could have done
when /Users/Mike/ccl-1.7-dev-r14869/foo/bar/ didn't exist....
That's why it would help if you would be more specific about what you want.
