I have a similar setup, except with multiple files importing from 
imported file.  One way to make absolute imports within a package work, 
and how I do it, is to put the directory containing testpkg in a .pth 
file in the site-modules directory.  In particular, I have python.pth 
containing "F:/Python".  This effectively makes "Python" an extension of 
'site-packages', so when site-packages is searched for modules, so is 
Python.
