Siegel.ie: [FIXED!] GData 1.2.0 and no module named alt.appengine

Just read Jeff Scudder's comment on my recent UpgradeSessionToken post. He pointed out that there is a newer gdata API which externally appears to be a minor change in the API usage. OK. Here goes!

He references the gdata docs which for my app required these changes (consolidated in a diff-like listing):

-import gdata.spreadsheet.service
+import gdata.service
+import gdata.alt.appengine
-gdata.service.http_request_handler = gdata.urlfetch
-gd_client = gdata.spreadsheet.service.SpreadsheetsService()
+gd_client = gdata.service.GDataService()
+gdata.alt.appengine.run_on_appengine(gd_client)

Great! Now we run the app and...

<class 'django.core.exceptions.ViewDoesNotExist'>: Could not import myapp.admin.views. Error was: No module named alt.appengine
Traceback (most recent call last):

Realized the article referenced an updated codebase released two days ago. The code affects the gdata and atom packages/directories. I'm not sure whether I downloaded the client code previously, or if it was created by google's app creation helper, but I had aging copies of the library in my project locally. So, I downloaded the updates and replaced the files:
