Thank you very much for your advice. I have correct these problems and re-upload to mentors.debian.net. I am not managing the patch with quilt etc. Because it is really a small update from upstream and the patch from me is really tiny. But quilt is a very nice patch managment tool. Thank you for your recommendation. Thank you again for your help. I am very appreciated. -- LIU Qi me@liuqi.org liuqi82@gmail.com liuqi@ict.ac.cn
