Thanks a lot guys.  The problem was that I was filtering using
directory-exists? on the valuesa returned by directory-list.  I needed
to append those values onto my base path in order for this to work. 
So my filter should have looked like this:

(filter (lambda (d) (directory-exists? (build-path dir d)))
(directory-list dir))

Also, I the example I provided was entered directly in my email (not
copy paste from source).  Sorry about the parenthesis confusion, I'll
make sure not to leave any stray from now on.
