Description Zac Medico gentoo-dev 2015-11-24 08:24:19 UTC
When there are unsatisfied conditional USE dependencies, emerge will report an unsatisfied dependency and suggest a USE change as follows 

emerge: there are no ebuilds built with USE flags to satisfy "dev-python/mock[python_targets_python2_7(-)?,python_targets_python3_3(-)?,python_targets_python3_4(-)?,python_targets_jython2_7(-)
!!! One of the following packages is required to complete your request:
- dev-python/foo::gentoo (Change USE: -python_targets_jython2_7)

It would be nicer if emerge converted the "Change USE" suggestion into an autounmask change which can be automatically written to package.use when --autounmask-write is enabled.
