Having done

$ ./dx86cl64
Welcome to Clozure Common Lisp Version 1.3-r12926M  (DarwinX8664)!
? (rebuild-ccl :full t)
...

It always frustrates me that this happens

bash-3.2$ scripts/ccl64
Can't find CCL directory.  Please edit scripts/ccl64 or
set the environment variable CCL_DEFAULT_DIRECTORY
and try again.
bash-3.2$

The following patch resolves the problem.   The problem is that  
readlink returns nothing when the given file is real, rather than a  
link.

And, thanks for the work you all do! - ben
