Bug#803082: [Python-modules-team] Bug#803082: ipython ftbfs (too new lessc version)

[Brian May]

I suspect the solution to this is to update to use ipython 4.0.0

It looks like there have been significant structural changes in 4.0.0,
so work is required to merge the patches (conflicts occur due to missing
files) and update debian/rules.
