Description Patrick Lauer gentoo-dev 2014-10-17 08:07:05 UTC 
Example:

[ebuild  N     ] dev-lang/hy-0.10.1  USE="{-test}" PYTHON_TARGETS="python2_7 python3_3" 0 KiB
[nomerge       ]  dev-python/flake8-2.1.0  USE="{test}" PYTHON_TARGETS="python2_7 python3_3 (-python3_2) -python3_4" 
[ebuild  N     ]   dev-python/mccabe-0.2.1  PYTHON_TARGETS="python2_7 python3_3 (-python3_2) -python3_4" 5 KiB
[ebuild  N     ]    dev-python/flake8-2.1.0  USE="{test}" PYTHON_TARGETS="python2_7 python3_3 (-python3_2) -python3_4" 25 KiB

Total: 3 packages (3 new), Size of downloads: 30 KiB

 * Error: circular dependencies:

(dev-python/mccabe-0.2.1:0/0::gentoo, ebuild scheduled for merge) depends on
 (dev-python/flake8-2.1.0:0/0::gentoo, ebuild scheduled for merge) (runtime)
  (dev-python/mccabe-0.2.1:0/0::gentoo, ebuild scheduled for merge) (buildtime)

It might be possible to break this cycle
by applying the following change:
- dev-python/flake8-2.1.0 (Change USE: -test)

This is subtly wrong, it should be FEATURES="-test". This useflag/feature is the only place where this happens, although adding a special case just for that is ugly ...
