[gambit-list] Questions about emacs gambit.el

I went looking around the internet and couldn't find a good answer so, I figure asking the list is about the best place to start ... I went through the documentation and set up my .emacs file to have the correct stuff to use gambit. So, when I have the buffer ... I try using C-c C-c and get back "unbound variable: compile" when I try to use the in-emacs scheme window ( m-x run-scheme ) and do a (define (square x) (* x x)) I get back ill-placed define ... what additional information can I provide to help get things all better. ?? Thanks, in advance for your time. jd
