Unbound variable: ESTYPEPTR

[Enrico Franconi <franconi@irst.it>]

I'm using MCL 2.0b1p3.
When I load the file ...:Library:SCROLLERS.lisp I get the following error:

;Loading "LENINGRAD:Lisp:MCL 2.0:Library:SCROLLERS.lisp"...
> Error: Unbound variable: ESTYPEPTR
> While executing: SYMBOL-VALUE

 From the backtrace I deduce that this is connected with the fetching of
the record type :RECT. A type with name RESTYPEPTR exists, but I couldn't
find anything in the source listings named ESTYPEPTR.
I need to load "scrollers" in order to use the "grapher" code provided in the
examples folder (which requires "scrolling-windows", which requires 
"scrollers").
Can someone help me?
Thanks
