Making PR #708 more concrete Now a check is made whether PYTHONPATH is set at all. So 'normal' installations will pass that section. After that sys.path is checked whether the last element is PYTHONPATH. If it is PYTHONPATH will be moved before entry at sys.path[1], because sys.path[0] is os.curdir. Inserting PYTHONPATH in front of it might be unsave.
