akonadi-server has the mysql use-flag. I disabled mysql globally in my make.conf. However, there is no point disabling the mysql-backend as there is no other. This FAQ describes the situation (section 5): http://techbase.kde.org/Projects/PIM/Akonadi#Akonadi_FAQ Further, if one tries to run the akonadi-service without mysql, it crashes heavily (see below). To fix this, I'd suggest to force the mysql usage on akonadi-server. $> akonadictl start Starting Akonadi Server... done.

While at it, also require USE=mysql for x11-libs/qt-sql ...
Thanks for the report. Sounds like mysql should be a hard dependency until at least one of those other databases is supported. Assigning to maintainers.
akonadi has by default +mysql and kde requires the akonadi-server with mysql enabled by default. so there is really nothing much to fix.
