Ok, new to Emacs, LISP and LTK, trying to follow along with the LTK tutorial, I am able to compile LTK and load it, but when I run the hello-l example I get the following

EVAL: undefined function WITH-LTK

   [Condition of type SYSTEM::SIMPLE-UNDEFINED-FUNCTION]

The tutorial says I need TCL/TK , which I got the source for, but how do I compile them or make LISP aware of them?
