Since c2d4u is (for the most part) automatic, it only grabs depends from
the CRAN web page. Therefore, there is no r-api-nn dependency for
packages built from c2d4u source packages. How that effects things is
unclear. As Dirk just posted, it was an executive decision that we made
(or possibly ignored).
However, sometimes I need to borrow a package from Debian (when someone
else has built it on Launchpad before I did), and those will have the
r-api-nn dependency. There are also the universe packages.
From my end, this is a mess. Rebuilding the universe packages for 3.5
is a slow process (crazy dependencies). Plan is to build everything
against 3.5, but it will take some time.
