Add a 

(eval-when-compile 
  (debug-print 
   "lisp-directory is %s, exec-directory is %s, mule-lisp-directory is %s"
   lisp-directory exec-directory mule-lisp-directory))

to one of the files in question, and try again. mule-lisp-directory should
correspond to a directory with ccl.el in it; I suspect the package compile
environment either picks up an older installed xemacs-21.5 binary when you
wanted to use one that is running in-place, or it confuses the
path-searching code of the desired binary sufficiently that it thinks
mule-lisp-directory is under the installation prefix.
