[plt-scheme] Scribble for PLaneT packages

Hi all,

I'm writing Scribble documentation for some PLaneT packages and I'm  
having trouble with my @defmodule forms.

I'm putting all my documentation in the directory "$PACKAGE_ROOT/doc",  
and all my source code is in the directory "$PACKAGE_ROOT". For example:

   /my/home/directory/unlib/list.ss    and
   /my/home/directory/unlib/doc/list.scrbl

I started out trying to use defmodule forms like:

   @defmodule[(planet untyped/unlib/list) #:use-sources ((file "../ 
list.ss"))]{ etc ... }

When I used "setup-plt -P" to build the documentation on my Mac, the  
build process failed because it was looking for "/my/home/directory/ 
list.ss". I figured this was because setup-plt resolved filenames  
relative to the root directory for the package, so I changed the forms  
to:

   @defmodule[(planet untyped/unlib/list) #:use-sources ((file  
"list.ss"))]{ etc ... }

The docs build fine now for me, but my colleague gets an error on his  
Linux machine saying setup-plt can't find "/his/home/directory/list.ss".

Am I doing this wrong or is there some sort of discrepancy?

Cheers,

-- Dave
