something I wrote a while back that works:

def getFilesInDirectory(dir)
   Dir[File.join(dir, "*")].collect do |f|
     if File.directory?(f) then
       getFilesInDirectory(f)
     else
       f
     end
   end.flatten
end

then you can use it like:
getFilesInDirectory(Dir.pwd).each do |f|
	puts f
end
