Hi,
Following the instructions on
https://deltacloud.apache.org/install-deltacloud.html , i've just build
the latest deltacloud on a debian7 amd64 .
Then i run:

/usr/local/bin/deltacloudd -V -i arubacloud -p 10000 -r IPADDR

and if i connect to the web interface, i immediatly get an error that
it's written on the logs:

--------------------------

One or two years ago i've built deltacloud on a debian6 and i didn't get
any error, now there's a way to solve this error?

Thank you,
