Consider this very experimental, and remember that I'm not an expert so
I may have made some mistakes:

You can change the dependencies in a deb package by editing its
"control" file.  You can do this in Gnome by right-clicking on the deb
file and choosing "open in archive manager" (or something like that).
Then do the same for control.tar.gz.  Then navigate the directory tree
to find a file called "control".  Open that and edit the "Depends" line.
 The syntax is fairly obvious.

You need to make sure you don't change "Depends" in such a way that the
application won't work.  If backuppc 3.1 will really work with the older
versions of samba (or if you don't use samba with backuppc), then there
should be no problem changing the depends line.

Hmm, I'm not sure, but you might get an error about the signature not
being valid when you install your modified deb.
