The stacktrace is telling you what is going on.

return os.path.join(tempfile.gettempdir(), cache_directory) 

 raise NotImplementedError("Only tempfile.TemporaryFile is available for use")  

As you already know you can't write to the filesystem in appengine, so 

having a function in the tempfile module that starts to play with the filesystem isn't going to work

so that lib has been replaced in the appengine runtime, with all of the non functioning methods/functions

changed to raise NotImplementedError.

This means out of the box (or with your specific use) of the twitter.py won't run on appengine.

Have a look through the groups here, people have had the same problem in the past, and 

have probably worked out how to access twitter api without creating temporary files.
