I worry you are straying very far from the beaten path and making a
lot of extra work for yourself.

pip as documented in our INSTALL.txt and my e-mail on usage under XS
0.7 should be doing all of this legwork for you, and ensure you are
getting the proper versions.

Without gcc and your rpm dependency hell this is difficult.  I'd
really recommend figuring out how to fix that because your platform is
really broken.

Even with broken gcc, I recommend you use pip to install all
pre-requisites except SQLAlchemy and lzma (which require gcc).  A list
of pre-requisites is in the IIAB repo file requirements.txt:

Flask>=0.10
Flask-Babel>=0.8
Flask-SQLAlchemy>=0.16
Flask-AutoIndex
Whoosh>=2.4.1
backports.lzma>=0.0.2

This flask.babel import problem was fixed last week when you first
reported it.  pip install --upgrade Internet-in-a-Box should correct
it, or get the latest code from github.

This is probably because CentOS 6.2 has a very old version of
SQLAlchemy installed via RPM.  Again, pip will install a compatible
version, but you won't be able to install it without gcc.

A longer term alternative to using pip that removes the gcc
requirement is for us to generate you CentoOS/XS0.7 specific RPMs.
This is what we are doing for XSCE, although there would be extra work
required because CentOS 6.2 is so far out of date compared to Fedora 18.

I'd be interested in more information why your attempt to install IIAB
on Ubuntu 12.04 failed.  That is our main development platform and is
pretty well tested.
