I have fixed a bug in osicat 0.4.0, which I just got from cliki via asdf-install. As is, it didn't create the right kind of library for Mac OS X (10.3.4).
The fix is simply to replace "-bundle" with "-dynamiclib" in osicat.asd, like this:
(defvar *gcc-options* '(#-darwin "-shared" #+darwin "-dynamiclib" "-fPIC"))
