I am running XEmacs 21.4 under Windows NT (NVS operating system). The ess 
version (very old) provided with the installation does not recognize Rnw 
files.  I have downloaded 5.13 but ess-site.el fails.  The message from 
the lisp compilation of the buffer is "Symbol's definition is void: 
ess-uniq-list". I have actually tried with numerous versions between 5.3 
and 5.13: with no solution to the problem.

The problem appears in the very long definition of ess-versions-created in 
the ess-site file. For earlier version it is in the equivalent part where 
all the ess-versions are defined.   I am not a lisp programmer, and do not 
intend to become one.  My system setting which I am not free to change 
appear to dislike the syntax. 

In earlier versions I could simply comment out the offending portions 
because I am not interested in the functionality to run programs, only the 
editing. Now when I do the same the dependencies created apparently make 
Rnw unrecognizable.  XEmacs won't even load the file.

How can I solve it? The use of ESS to edit for Rnw files (which is great) 
is key for my work.

Many thanks for your help

Georgina
