Hi Julien (note: this is probably for Upstream not Debian)

But then which file should >I point to? "some of functions is derived from *" lets ignore grammar, I guess this means "some of the functions in the source code, have been derived from foo/bar" so, you need to ask them which functions, or maybe release under FOO and BAR and FOOBAR licenses the whole package. I'm not sure, but copying files with a different copyright shouldn't be ignored, if you can't know which files have such licenses, my suggestion is to relicense the whole package. But as said, this is something for upstream. G.
