Description François Bissey 2016-03-01 10:21:26 UTC 
When emerging ipython with the qt4 useflag there is a circular dependency:
 * Error: circular dependencies:

(dev-python/qtconsole-4.2.0:0/0::gentoo, ebuild scheduled for merge) depends on
 (dev-python/ipykernel-4.3.0:0/0::gentoo, ebuild scheduled for merge) (buildtime)
  (dev-python/ipython-4.0.3:0/0::gentoo, ebuild scheduled for merge) (buildtime)
   (dev-python/qtconsole-4.2.0:0/0::gentoo, ebuild scheduled for merge) (runtime)

It might be possible to break this cycle
by applying the following change:
- dev-python/ipython-4.0.3 (Change USE: -qt4)


It could be broken by initially emerging ipython without qt4 but it could be solved at the ebuild level by moving qtconsole from RDEPEND to PDEPEND (as was done before for ipyparallel for exactly the same reasons).

Reproducible: Always
Comment 1 François Bissey 2016-03-01 10:22:35 UTC 
Moving qtconsole from RDEPEND to PDEPEND in the ipython ebuild I meant. This applies to all ipython-4.* ebuilds.
