You are saying you only want dependencies listed in the "Depends" field 
of DESCRIPTION.  Many packages nowadays have dependencies listed in 
"Imports", because that's now the recommended way to do it.  Those are 
not optional.

Imports are loaded, but don't affect the search path, so that's why 
they're preferred over Depends, which are both loaded and attached to 
the search path.  Modifying the search path can break user scripts.
