Cannot find gnuradio.i in 3.6.1

Hi all,
I updated to gnuradio 3.61 and previously working applications are not
working. I tried recompiling the UCLA packet sniffer and I get errors on
the make.
It seems there was a similar case that was resolved on this link,
http://www.ruby-forum.com/topic/4040797 , however I can’t get where to
make the changes for the error to vanish.
Should I paste this
diff --git a/gr-howto-write-a-block/Makefile.common
b/gr-howto-write-a-block/Makefile.common
index fca6133…2b9cc75 100644

In my Makefile.common of my application?
