Recent versions of nepomuk-core require a newer soprano. kde-base/nepomuk-core-9999 (from the kde overlay) should require: >=dev-libs/soprano-2.8.90 instead of: >=dev-libs/soprano-2.8.0 Reproducible: Always
Created attachment 334220 [details] Build log showing the error in the configure phase.
Sorry, as shown in the build log now it should be: >=dev-libs/soprano-2.9.0
Whoops, sorry about that. Fixed.
