It's also possible that the error message is misleading and the
underlying error being swallowed if six is doing something fancy.  For
example, I seem to remember a bug in the unittest module where, when
loading tests (to use the example above), an error processing the
parse module would show up as an error like the above ("ImportError:
No module named urllib").
