Hi John,

you are definitely right, we should solve the infinite loop ;)

its happening here:

 >          while tail != 'lib' and head != '':
 >              head, tail = os.path.split(head)

 >>> get_path("platlib")
'/home/pr/work/projects/5t-roundup/ve2/lib64/python2.7/site-packages'

it consumes everything (as no "lib" anywhere) and stays at head == "/"

 >>> os.path.split ("/")
('/', '')

so maybe exit the loop with "error" if head == "/" and tail == ""

marcus.
