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.
Three out of two people have difficulties with fractions.
