def rename( headOfTree, what, withWhat )
	p = Pathname.new( headOfTree )
	p.each_entry do |file|
		path = file.to_s #just to make it prettier
		next if path =~ /^\.\.?$/
		rename( path, what, withWhat ) if path.directory?
		File.rename( path, path.gsub( "#{what}", withWhat ) ) if  
path.include?( what )
	end
end

This code is untested, but if you recurse before you rename, you  
should get what you want.
