This is probably due to something François Bissey pointed out to me and
Jason Grout earlier in an email - the setup.py for sagenb doesn't
actually install the flask_version directory found in the main sagenb
directory, so sagenb fails to work unless you run `setup.py develop`
(rather than, or in addition to, `setup.py install`).

So try `setup.py develop` in the sagenb directory and see if it starts
working. This is probably a bug, though 1) it doesn't affect anyone
installing sagenb automatically as part of the Sage installation process
because we use `setup.py develop` in the build script for the sagenb
SPKG, and 2) maybe there's some good reason for it to be this way which
I'm not seeing (?).

Alternatively you could apply this patch to the sagenb sources:
https://github.com/cschwan/sage-on-gentoo/blob/master/sci-mathematics/sage-notebook/files/sage-notebook-0.9.0-setup.py.patch
(François decided to just go ahead and fix this - maybe we should just
do so in sagenb as well.)
