Hi Tony,
Thanks for catching this.  It was a versioning issue with the latest
version of the Flask-Babel dependency.

I have fixed it in version 0.4.9 and pushed it to PyPi just now.  It
should work for you if you run:

sudo pip uninstall Internet-in-a-Box
sudo pip install Internet-in-a-Box

What version of CentOS is School Server 0.7 based on?  Is there an ISO
for XS 0.7 we could install to a virtual machine for testing here?

Is it normal to install a school server without internet access at
install time?  There are several approaches we could work out if that
is the case.  We could build a local repository of RPMs if that is
necessary, or make a python virtualenv with all of the dependencies in
one tarball.

I have not tested with python 2.6 for several months, it is very
likely broken - but probably easy for us to fix.

backports.lzma is our most troublesome dependency, unfortunately it is
necessary to read the ZIM file format that all the wikipedia dumps
from the Kiwix community are in.  We have tried alternatives but
nothing really cuts it.

Sounds like you are in "dependency hell" independent of IIAB.

We will get you up and running one way or another.
