It works fine with 0.10.3.1. The error is caused by the line 55-57 move down to the end of file licalstack/config.py:
```
 if TMP_FOLDER.startswith('/var/folders/') and os.path.exists('/private%s' % TMP_FOLDER):
    TMP_FOLDER = '/private%s' % TMP_FOLDER
```
These lines setup Mac TMP folder. Why these lines were moved?
