Well, pkg_add *already* gets the list of dependencies from the .tbz file
that it is either passed on the command line or it downloads.  I believe
that Anton is asking for a bit more separation between the "fetch all
packages to be installed" and the "install all fetched (fought?) packages"
phases of pkg_add's operation.  However, given the way that pkg_add
operates by invoking itself recursively, it might not be easy to do this
without a major rewrite and algorithm change.

G'luck,
Peter

No language can express every thought unambiguously, least of all this one.
