As per: http://trac.osgeo.org/osgeo/ticket/1271
We need to resolve versions between IRIS and IPython.
numpy, matplotlib, scipy should be pulled once or else the build process 
takes forever to complete.

BTW, I don't see IPython listed as a supported/included OSGeoLive project.
Can someone please step up to create Quickstart/Overview and be the 
maintainer for it?
I know we agreed to let it in in previous releases, but since 
maintaining it now creates conflicts/interactions with other projects we 
need to have a maintainer for it. Thoughts?

Best,
Angelos
