[IIAB] iiab problems

Hi, all
I have narrowed the problem down to the use of gcc to build the
backports.lzma.
After several hours of scrambling, I have managed to mess up the gcc
install beyond all hope of redemption.
My current strategy is to set up a CentOS 6.2 repository on the school
server (still plenty of room!). I should be able to use yum to install gcc.
Looking forward:
What you installed I see as the base system (what CentOS calls the
minimal system). The idea is that this system supports administration by
ssh and is a functioning server.
Daniel Drake developed a method using usbmount to install additional
packages and content from a removable device simply by mounting it.
This is how I would like to install and set up IIAB since that can be
used at each of the deployments with minimal technical supervision.
In this context it would be good to have as much of the install done
before creating the removable drive (e.g the lmza package built). I like
the idea of using pip - I haven't been able to get it installed on the
school server.
However, if this local repository concept works, the scripts can make
full use of yum to install such packages.
I have read internet comments that suggest installing gcc on a server is
not a good idea - it provides a lot of tools for hackers.
Anyway, the first priority is to get internet-in-a-box installed and
running.
Thanks for your help on this. It is greatly appreciated.
Yours,
Tony
