Hi Tong! How are you?
I checked your package again and I saw you are using two patch to
override a Makefile self change.
The correct action is say to DH to ignore changes in file. You can use
this patch:
--- shc-3.8.9.orig/debian/source/options 1969-12-31
21:00:00.000000000 -0300
+++ shc-3.8.9/debian/source/options 2014-06-11 12:46:12.878450159 -0300
@@ -0,0 +1 @@
+extend-diff-ignore = ^Makefile$
So, you can remove the Makefile patches.
A good news for you: I am in last step to become a DD. I think that I
need wait a month or less. So, I will can upload your package.
Have a nice day!
Cheers,
Eriberto
