So far I have received a code signing identity from the apple developer page, create an authenticated certificate which is in my key chain but when I execute the codesign command in the OSX terminal I get some strange errors:

I was able to find some threads discussing similar issues but the thread and solution always seemed to assume that the project was an XCode project and offered little assistance for my CCL app.  

This error happens when trying to sign a binary that is a heap image with a prepended lisp kernel.  The codesign command chokes on that, as you note.

Sometime around the 1.7 release, I changed the lisp kernel so that it will also try to find a heap image inside .app bundles.   When it wants to load a heap image, the lisp kernel tries the following places in order:
  * image pathname specified on command-line
  * embedded image
  * same directory as the lisp kernel binary
  * ../Resources/ccl/, relative to the directory containing the lisp kernel binary.  (Since the lisp kernel would be MyApp.app/Contents/MacOS/dx8664cl, this lets us have a lisp image in MyApp.app/Contents/Resources/ccl/dx86cl64.image.)

I wrote a crude script to construct and sign the Mac App Store version of CCL.  It's not in the trunk, but you can look at it at http://trac.clozure.com/ccl/browser/branches/1.8-appstore/source/scripts/make-store-app.  Maybe it will help you.
