Meant to be .py, right? :)

Certainly this behaviour is intended - Python finds the
first occurence of Package1 in the path, and initialises it.
Subsequent checks for module contents are then done on the
already-initialised Package1.

The first recommendation here is, of course, is to eliminate
your problem by refactoring your packages. If this is
impossible, however, you may be able to do something like:

sys.path.insert(0, '/home/david/usr/lib/python')
import Package1.Libra
sys.path.insert(0, '/home/david/proj/Proj1/lib/python')
import Package1.Scorpio

But don't do this if you can help it.
