debian .orig.tar.gz vs. upstream tar.gz
I got hit by this so I wanted to note it down where it might be of
use to others. It *is* elementary but then ...
Suppose pkg_123.45.orig.tar.gz is already in the Debian archive.
To build a new version pkg_123.45-xxx of the Debian package.
*Always* use the Debian version of the .orig.tar.gz by doing "apt-get -d source pkg".
Do *not* get the upstream .tar.gz which may have changed for some
Do *not* depend on a local .orig.tar.gz as it may also have changed for
some other mysterious reason.
