what to do when upstream package is shipped with MB of dependencies ?

[Jérémy Lal <jerry@edagames.com>]

I'm in a situation where upstream tarball is not very nice;
e.g. it's shipped with 3MB of dependencies, most of which
are already packaged.
I suppose a patch has no meaning here, since it consists in
removing the dependencies from the tarball. Another patch consists
in correcting the makefile to use already installed libraries instead
of rebuilding them. That one could be meaningfull.
Is doing a get-orig-source taking care of cleaning up upstream
a good solution ?
