a few days ago, I asked a few questions, but unfortunately nobody
bothered to answer. May I ask again?

This one has been solved in the mean time:

        ( cd foo/src && make )

        ( cd foo/src && make install )

        ( cd foo/bin && rm -f binary1 binary2 )
        ( cd foo/src && make clean )

I don't know if it is the best way to do it.

I didn't dare setting DEB_BUILDDIR.
