    bin: fix path settings to never include empty path elements. fix typos
    
    Things like PYTHONPATH="foo:$PYTHONPATH" are bad, because if
    PYTHONPATH isn't previously set, you'll end up with a "" element in
    it, which will be interpreted as ".", which you don't want.
    
    Use some tricky bash syntax to say "add : and $PYTHONPATH if
    PYTHONPATH is set".
    
    Also fix a few typos ("licaribou", etc)
