[ckan-dev] ckanext-datajson installation issues

Hopefully the line numbers will change, proving that the new import
was inserted into apache.wsgi and apache is rereading it.

There is some circular dependency thing going on. apache.wsgi imports
paste.deploy, which in turn imports the DataJsonPlugin and that in
turn pulls in ckan's toolkit and that tries to import paste.deploy
again. It's certainly something that crops up for people occasionally
when installing extensions.
