I think so. To the best of my knowledge, we don't do anything explicitly.

There is really just a Depends: on whatever is needed to run the
code. E.g. because we build against libibverbs, the libopenmpi1
library package ends up with

   Depends: libc6 (>= 2.7-1), libgcc1 (>= 1:4.1.1-21), libgfortran3 (>= 4.3), \
        libibverbs1 (>= 1.1), libstdc++6 (>= 4.1.1-21)

which is rather standard.

Yes, that sounds fine.

Hth, Dirk
