[racket] Scribble Warning / "on this page"

Do you have a `defmodule' declaration? That is, your documentation
source should look something like this:

 #lang scribble/manual
 
 @(require (for-label racket
                      mylib))
 
 @title{Documentation}
 
 ...
 @defmodule[mylib]
 ...
 
 @(defclass porte% object% {and% or% not% nand%}

Of course, you'd use something else for `mylib' --- whatever your
library is called --- but I'll assume `mylib' here.

The `@defmodue[mylib]' indicates that documentation in the enclosing
section is for bindings from the `mylib' library. It generates typeset
output of the form

 (require mylib)

in a beige box so that a reader of the documentation knows that it's
for the `mylib' library, but it also cooperates with `defclass',
`defproc', etc., so that they know they're documenting classes,
procedures, etc. for `mylib'.

I also added `mylib' to the `for-label' imports above, so that every
use of `porte%' will be hyperlinked to the definition (in the same
section) of `porte%'.

You shouldn't need to set up a tag to hyperlink to the definition of
`porte%' or a function documented with `defproc'. Instead,
`@racket[porte%]' in any context that imports `(for-label mylib)'
should cause the typeset `porte%' to be a hyperlink to the definition.

The "On this page" box on a page's left-hand side is similarly
generated automatically. I'm not sure why you're aren't seeing it
already, but maybe it has to to with the other problems, so let's sort
out those first.
