I have to say, it takes me even now more than a few seconds for the light to go on when I get one of these errors, perhaps because the error is never "unknown symbol", CL just makes a new one in the current package and then finally gives the warning "function undefined". This gets especially nasty when we are doing GFs and we really do have methods defined that miraculously are not being run (because we end up with two GFs, one on each symbol).

So anyway, the moral is, "When an error makes absolutely no sense, or when a method that should run is not running, think "package error".)
