It is still not quite clear, what you try to achieve. Packaged procedures/functions as opposite to packages are not database objects, so dependencies are not stored. You can have call to package B within package A which don't belong to any function/procedure - for example in the initialisation block, or you can reference global types too from the package body itself.
If you goal is to estimate which lines in your packages should be modified after you change the referenced package - you still need to parse the source code. Every decent editor with can do it for you. (or you code it in plsql, should be not that complex).
