I am trying to set up a Google CourseBuilder site on a RHEL server. I follow the instructions here and get the server running. However every request errors out with the following message. I have not changed any configuration from the provided package and a similar approach worked on Windows 8.
ERROR 2013-03-07 16:05:10,337 dev_appserver_import_hook.py:1251] Third party package markupsafe was enabled in app.yaml but not found on import. You may have to download and install it.
INFO 2013-03-07 16:05:10,412 dev_appserver.py:3104] "GET / HTTP/1.1" 302 -
What is strange is that the markupsafe package is already in .../google_appengine/lib/markupsafe-0.15
Any ideas how to fix this?
