I ran into a similar problem when trying to add new functionality to someone else's script. I wanted to provide my solution in case anyone else runs into a similar issue.

In this case, there was a '(let* (...))' statement that was being used to initialize some variables. The original author of the script wrote '(let * (...))' - with a space between let and star - which means every vector in the 'let' statement becomes the expected arguments for the '*' statement.

More info: http://docs.racket-lang.org/reference/let.html

Please excuse (and correct if necessary) any incorrect nomenclature regarding Scheme. I have barely just been exposed to it.
