Ruby xml-mapping: `write': undefined local variable or method `output'

I’ve been working with the XML-Mapping gem and had the following error when trying to generate XML:

/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rexml/element.rb:685:in `write': undefined local variable or method `output' for <xml_node> ... </>:REXML::Element (NameError)

A bit of digging lead me to this bug report, which lead me to look properly at the code and sure enough correcting the code (line 674) corrects the bug and I can generate XML. i.e. changing

def write(writer=$stdout, indent=-1, transitive=false, ie_hack=false)

def write(output=$stdout, indent=-1, transitive=false, ie_hack=false)

Note that writer has now become output. Now since that whole function in REXML is depreciated anyway I should probably modify the XML-Mapping code to use the more modern REXML::Formatters, but this sorted the immediate problem.
