I got the same error message as you did Jari.  But I did find the REXML 
changelog, which shows the revised method to get pretty printing. This 
worked for me.

Addresses ticket:85

This is a major rewrite of the XML formatting code. The XML writers have 
all
been extracted out of the classes and put into their own class 
containers.
This makes writing parsers easier, and cleaner.

There are three formatters, which correspond to the previous three XML 
writing
 modes:

REXML::Formatters::Default
Prints the XML document exactly as it was parsed
REXML::Formatters::Pretty
Pretty prints the XML document, destroying whitespace in the document
REXML::Formatters::Transitive
Pretty prints the XML document, preserving whitespace

All of the write() functions have been deprecated (some are still used, 
but
these will also go away) except the write() function on Document, which 
is left
for convenience. To pretty print an XML document the canonical way:

formatter = REXML::Formatters::Pretty.new( 5 ) # indent by 5 spaces
formatter.write( document, output
