The script currently does the following:

* Invokes pkg_chk to get an initial list of stuff that is out of date
* Walks up the installed dependency tree to add to the list all packages 
which depend on anything already in the list
* Removes from the list any packages which are dependencies

This leaves us with a list of packages which are at the top of the tree, 
which need building. In your example, ORBit and tiff would be expanded 
to everything that depends on ORBit and tiff, and would then be reduced 
to top-level packages, such as meta-pkgs/kde3.

pkg_comp is then instructed to build meta-pkgs/kde3, which pulls in 
everything else as dependencies.

pkg_comp is set up to use binary packages where available, so tiff would 
be installed from a binary package rather than rebuilt.

In general, you can't do this. You need your binary packages not only to 
be internally consistent, but also consistent with respect to the other 
packages on your system.

You can't, for example, update tiff until *everything* that depends on 
tiff is ready to be updated as well. You need two complete trees which 
do not share a common node, which in practice does not happen very often 
at all in pkgsrc.
