^- So indeed, /tmp/bar is in your path.

What I've seen in the past, is that if you insert debug statements into
*site.py* it gets a '' in sys.path, and then it calls a function to turn
all paths in 'sys.path' into absolute paths (and thus '' => $PWD).

Obviously you are getting $PWD into your path somehow, the question is
figuring out how.

For bzrlib, one possibility could be to do:

cwd = os.getcwd()
bzr_path = os.path.dirname(sys.argv[0])
if bzr_path != cwd:
  while cwd in sys.path:
    sys.path.remove(cwd)

Alternatively, if we do it in the 'bzr' main script, we can change the
line to:

bzr_path = os.path.dirname(__file__)
