*I suspected*, because when I force to upload a CSV file via web interface,
I eventually get the error "Process completed but unable to post to
result_url" then, when I hit "send data to datastore" multiple times, the
error changes to "File "/usr/lib/ckan/datapusher/lib/

I found the version at file /usr/lib/ckan/datapusher/src/datapusher/
datapusher.egg-info/PKG-INFO,* it says Version: 0.0.8*
