i'm not sure why you are unable to import uno (assuming uno is at ~/
hacking/python/uno.py) after exporting the PYTHONPATH variable. an
alternative way to incorporate uno is to change sys.path, the list of
search paths

     import sys
     sys.path.append(os.path.expanduser('~/hacking/python'))
     import uno
