that ssems unlikely, as does the possibility that a file named 
"ccl-ide-init.iisp" is not loaded by the CCL IDE when such a file
is present in the user's home directory and no one but you has ever 
noticed that.

When you call LOAD, what arguments are you calling it with and what 
values are returned by that call ?
what directory is the file being loaded from?
what does the file contain?  how did the curly quote get there ?
